When a port shares its pin with a bus control pin, such as address bus, data bus, CS, or RD, set its
corresponding Port Pi Register (i = 0 to 15) and Port Pi Direction Register after entering single-chip mode.
(Technical update: TN-M16C-49-0004)
Rewriting bits PM01 and PM00 in the PM0 register places the MCU in the corresponding processor mode
regardless of CNVSS input level. When setting bits PM01 and PM00 to 01b (memory expansion mode) or 11b
(microprocessor mode), do not set simultaneously with bits PM07 to PM02. 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.
When the MCU starts up in microprocessor mode, the internal ROM cannot be accessed.
