CPU Rewrite Mode (Flash Memory Version)
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
Flash memory control register 1 (FMR1):
Bit 1 allows the user to enter EW1 mode. This bit is relevant only if bit FMR01 is set.
Bit 7, when set to "0", inserts one wait state per access to Block A or B - regardless of the value of
PM17. Wait state insertion during access to all other blocks, as well as to internal RAM, is controlled
by PM17 - regardless of the setting of FMR17. In cases where E/W cycles to Block A or B exceed 100
times (D7, D9, U7, U9), please set FMR17 to "1" (with wait).
Flash memory control register 4 (FMR4):
Bit 0 must be set to enable the erase-suspend feature.
Bit 1 is to be used to request a suspend of an erase operation. This bit is set automatically in EW1 by
a maskable interrupt, and by software in EW0. This bit is to be always cleared by software at the end
of the erase suspend.
Bit 6 indicates suspend status. Poll this bit in EW0 after requesting a suspend, before accessing the
flash.
