4.1.8 RE (Wake Up Control Register)
Bits 0:
Bit 1 (ICWE): Port 6 input status change wake-up enable bit
Bits 2 ~ 7:
4.1.9
“1” means interrupt request, and “0” means no interrupt occurs.
Bit 0 (TCIF): TCC overflow interrupt flag. Set when TCC overflows. Reset by
Bit 1 (ICIF): Port 6 input status change interrupt flag. Set when Port 6 input changes.
Bit 2 (EXIF): External interrupt flag. Set by falling edge on /INT pin. Reset by
Bits 3 ~ 7:
RF can be cleared by instruction but cannot be set.
IOCF is the interrupt mask register.
4.1.10 R10 ~ R3F
These are all 8-bit general-purpose registers.

0 = Disable Port 6 input status change wake-up
1 = Enable Port 6 input status change wake-up
The result of reading RF is the "logic AND" of RF and IOCF.
