SWAIT — Stop-to-Wait Conversion Bit
The SWAIT bit enables halt mode. When the SWAIT bit is set, the CPU interprets the STOP instruction
as a WAIT instruction, and the MCU enters halt mode. Halt mode is the same as wait mode, except
that an oscillator stabilization delay of 1 to 4064 t
cyc
occurs after exiting halt mode.
1 = Halt mode enabled
0 = Halt mode not enabled
SWPDI — Software Pulldown Inhibit Bit
The SWPDI bit inhibits software control of the I/O port pulldown devices. The SWPDI bit overrides the
pulldown inhibit bits in the port pulldown inhibit registers.
1 = Software pulldown control inhibited
0 = Software pulldown control not inhibited
PIRQ — Port A External Interrupt Bit
The PIRQ bit enables the PA0–PA3
pins to function as external interrupt pins.
1 = PA0–PA3 enabled as external interrupt pins
0 = PA0–PA3 not enabled as external interrupt pins
LEVEL —External Interrupt Sensitivity Bit
The LEVEL bit controls external interrupt triggering sensitivity.
1 = External interrupts triggered by active edges and active levels
0 = External interrupts triggered only by active edges
COPEN — COP Enable Bit
The COPEN bit enables the COP watchdog.
1 = COP watchdog enabled
0 = COP watchdog disabled
