examples and Appendices
06/10/94 A 1 9401003 − 9441043 Added header file listings to sample 4284 setup code in Appendix A, Section A 1
07/08/94 B 9401003 − 9441043 Listed Pentek part # for ordering Comm Port cables Minor change to detail block diagram Add
section 4 8 on memory usage & table of transfer times
10/11/94 B 1 9401003 − 9441043 Changes to Tables 4−8 to properly represent transfer timing for 50 MHz 'C40 Delete Table 4−9 &
refer to 'C40 Manual for DMA timing info Changes to Sections 2 11 4 and 3 2 1, regarding which
signals are inputs and which are outputs
11/11/94 B 2 9401003 − 9441042 Correct pin numbering error in Table 2−12 System Clock jumper installed between pins 1−2, not 11−12
12/29/94 C 9441043 − Forward New features: Flash EEPROM and Turbo−MIX Properly identify jumper blocks SW1 and SW2 in
Figure 2−2 Expanded discussion of Reset Operation Add more transfer timing tables for 40 and
50 MHz parts, using block repeat, DMA and Turbo−MIX Descriptions of these tables updated
Turbo−MIX example added to Appendix A Flash EEPROM programming code added to Appen−
dix A Update Boot Code in Appendix B
01/27/95 C 1 9441043 − Forward Add info re:Option 010, in which A32 address is independent of A24 address, and Memory Window
jumpers affect A24 window only Correct Table 2−2 (A16 address 8700 is reserved) A24 inhibit bit also
prevents A32 access This change affects Section 2 4 3, Section 3 11 2 4, and Table 3−12
01/05/96 C 2 9441043 − Forward Mention FTL in Section 1 9 (Software Support) Add info on mating connector for front panel Serial
and GPIO connectors (Sec 2 11) Add Section 2 14, describing blinking of Front Panel LED on
power−up Correction to note in Section 4 2 1, reference to EPROM rev should be Revision E, not B
Indicate that use of the Linker Command File shown in Sections 4 3 1 and A 6 requires a change to
main Changes to Hex File Loader & Starter in Section A 7
09/10/96 D 9441043 − Forward Sec 3 8 5: 'C40 Int to VME Status bit in Transfer Mode Reg is accessible to the 'C40 (not VME) for read
only Add Tables & Figures to Table of Contents Update MIX Appendix to Rev F 1
07/02/97 D 1 9441043 − Forward IACK Vector Register must be re−written to clear VME interrupts generated by 4284 This infor−
mation added as a Note in Section 3 11 1, and to text in Section 4 6 1
09/22/97 D 2 9441043 − Forward Section 4 2 1 − The code that triggers a boot from Flash EEPROM is A55A 5AA5, not A55A A55A −
this changes the last paragraph on pg 52, the first paragraph on pg 53, Table 4−4, and the first
paragraph on page 57
05/04/98 E 9441043 − Forward Add Parallel C to Software Development Support section (1 9) Replaced board diagram with VSB ver−
sion of board Added section 3 12 on VSB Modified Table 3−7 to include VSB addresses
05/21/98 E 1 9441043 − Forward Revisions to VSB section (3−12) − renamed Table 3−14 (VSB Control Register) and renamed some bits
in the table Add Tables 3−15 − 3−17 illustrating bit field usages in VSB Control Register Add VSB
interface to Detailed Block Diagram (Fig 4−1) In SW Development Support section (1 9) Parallel C is
now called Diamond
7/23/98 E 2 9441043 − Forward Correct & cross reference to Table 3−16 in Table 3−14
10/12/98 E 3 9441043 − Forward Correct address range for VME Master Access in Table 3−7 (0xB000 0000 − 0xBFFF FFFF)
10/22/98 F 9441043 − Forward Regardless of DRAM Window size, DRAM must be mapped on an address bounmdary that is a multiple
of the actual DRAM size This changes text in Secs 2 4 2 and 2 4 3, and Tables 2−5 − 2−7, and deletes
Tables 2−8 & 2−9 (these tables all concerned base address vs window size) Add note to Sec 2 4 3 indi−
cating that for DRAM access, each ‘C40 address is equivalent to four VME addresses Reinforce same
concept in Sec 4 10 Give VME address of DRAM in Sec 3 10 & add a note to the ‘C40 memory Map stat−
ing that DRAM is shared w/ VME Sec 4 2 3 − Host Control Reset does NOT reset MIX or VSB Change
timer address in Sec A 4 (1st executable line under main()) to 0x100020 Remove MIX Appendix & refer−
ences to it (this info now included in 800 00001)
12/06/99 F 1 9441043 − Forward Sec 1 9 − Removed SPOX, FTL & Diamond from Software Support list Corrections to Tables 2−5 thru
2−7, which were correct up until last Rev Sec 2 1 2 1 − Comm Port Cable is Model 2104, not 2014 Table
4−3: Removed extra ‘0’ in last row of address column Added NOTEs to Sec’s 4 2 4 & 4 3 5 about initial−
izing the Local Control Register if you do not boot from the factory EPROM Remove Sec 4 4 2 (Down−
loading SPOX programs), and the sentence referencing SPOX in Sec 4 4
7/26/00 F 2 9441043 − Forward Sec 1−12: delete reference to Opt 060 Additional corrections to Tables 2−5 thru 2−7 Update Boot Code
