Bits PM01 and PM00
Single-chip mode, memory expansion mode, microprocessor mode, or boot mode can be selected as the processor
mode. Table 7.1 lists the features of the processor mode.
The CNVSS pin, EPM(P5_5) pin, and bits PM01 and PM00 in the PM0 register determine which processor mode
to select. Table 7.2 lists processor mode after hardware reset. Table 7.3 lists the processor mode selected by bits
PM01 and PM00.
Rewriting bits PM01 and PM00 in the PM0 register places the MCU in the corresponding processor mode
regardless of the CNVSS input level. When using memory expansion mode or microprocessor mode, first set bits
PM02, PM05 and PM04, and PM07 in the PM0 register, and also set bits PM11 and PM10, PM15 and PM14 in the
PM1 register. Then, set bits PM01 and PM00.
Do not enter microprocessor mode while the CPU is executing the program in the internal ROM.
Do not enter single-chip mode from microprocessor mode while the CPU is executing the program in an external
space.
The internal ROM cannot be accessed regardless of the PM01 and PM00 bits setting if the MCU starts up in
microprocessor mode after reset.
Figures 7.1 and 7.2 show the PM0 register and PM1 register. Figure 7.3 shows a memory map in each processor
mode.
