Software Reset
Writing “1” to bit 3 of the processor mode register 0 (address 000416) applies a (software) reset to the
microcomputer. A software reset has almost the same effect as a hardware reset. The contents of internal
RAM are preserved.
Processor Mode
Single-chip mode
M16C/62N (80-pin version) group support single-chip mode only.
In single-chip mode, only internal memory space (SFR, internal RAM, and internal ROM) can be ac-
cessed. Ports P0 to P10 can be used as programmable I/O ports or as I/O ports for the internal peripheral
functions.
Figure 1.8.1 shows the processor mode registers 0 and 1.
Figure 1.8.2 shows the memory map.
