READING THIS MANUAL
nPage Layout
In this manual, an entire section is presented on a single page or spread whenever possible.
The reader can thus view a section without having to flip pages.
The content of each section is summarized immediately below the title. You can obtain a rough
overview of this product by reading through these summaries.
Also, higher level section headings are given in lower sections so that you can know to which
section the text you are currently reading belongs.
nFinding information
In addition to the standard table of contents and index, the following methods are available to
find information in a particular section when required.
lRegister index
Information can be looked up in the register index by register name, by bit name, and by their
respective abbreviations.
lSub-heading index
The sub-headings in each section (lines that start with n) are collected together in the sub-
heading index. The sub-heading index provides a means of looking up information at a finer
level of detail than the table of contents.
nNaming Conventions for Register Name and Pin Name
lExamples for description of register name and bit name
By writing “1” to the sleep bit (STBC:SLP) in the standby control register...
Disable the interrupt request output (TBTC:TBIE =“0”) from the timebase timer.
Interrupt is accepted if the interrupt is enabled (CCR:I=“1”).
lNotations for shared pins
P25/SCK pin
The terminal contain the common pins which are programmably switched for different purposes.
The shared pins are described with each function name delimited by “/”.
