Description added.
The high-current port control register (PPCR) is an 8-bit
readable/writable register that is used to control six pins
(PE9/TIOC3B/SCK3/TRST*, PE11/TIOC3D/RXD3/TDO*,
PE12/TIOC4A/TXD3/TCK*, PE13/TIOC4B/MRES,
PE14/TIOC4C/DACK0, PE15/TIOC4D/DACK1/IRQOUT) of
the high-current ports.
This register is not supported in the emulator. Bits are always
read as undefined in the emulator.
Usage note added.
Bit No. amended.
Bits 15 to 0: → Bits 7 to 0:
Description amended.
When changing to boot mode, the boot program built into this
LSI is initiated. The boot program transfers the programming
control program from the externally-connected host to on-
chip RAM via SCI1. After erasing the entire flash memory,
the programming control program is executed.
