Notes on Differences between QzROM and Flash Mem-
ory Versions
(1) The memory map, the writing modes and programming
circuits vary because of the differences in their internal
memories.
(2) The oscillation parameters of XIN-XOUT and XCIN-XCOUT
may vary.
(3) The QzROM version and the flash memory version MCUs
differ in their manufacturing processes, built-in ROM, and
layout patterns. Because of these differences, characteristic
values, operation margins, A/D conversion accuracy, noise
immunity, and noise radiation may vary within the specified
range of electrical characteristics.
(4) When switching from the flash memory version to the
QzROM version, implement system evaluations equivalent
to those implemented in the flash memory version.
(5) The both operations except the electrical characteristics are
same at the emulator (emulator MCU board: M38D59T-
RLFS).
