1. Introduction
Writer8_U1Plus is AP of megawin’s writers(U1Plus). The PC-Site AP corresponding to
U1Plus supports megawin’s 8051 series 8-bit MCUs. In addition to writing the entire
flash area in On-Line mode, Writer8_U1Plus can also write MCU H/W Options.
Moreover, Writer8_U1Plus provides megawin’s standard ISP code and Off-Line mode
functions as well. This AP can also generate MPJ generation tools for customers.
megawin’s writers (U1Plus-D or U1Plus)
If only user connect U1Plus-D and DUT’s board through J9 connector(ICP Interface),
U1Plus-D can program DUT on board.

place it in the AP area (read into the buffer at 0x00) or IAP (users can define any
location to read into the buffer). Clicking “OK” to see update results in Code Buffer.
Users can Load File repeatedly and overlay files on each other. If users execute Load
File repeatedly, the overlapping file will be overwritten by the last file read. If there is
a blank between the read position of the previous and last files, 0xFF will be filled in.
Check “Clear Buffer” in the “Select Insert Area” dialog. After clicking “OK”, all the
Code Buffer will be cleared and then read into the File.
