General Description
MOTOROLA
PB2PU — Port B2 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 2.
1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
PB1PU — Port B1 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 1.
1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
PB0PU — Port B0 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 0.
1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
COPEN — COP Enable
When the COP option is selected (COPEN = 1), the COP watchdog
timer is enabled.
When the COP option is deselected (COPEN = 0), the COP watchdog
timer is disabled.
STOPEN — STOP Instruction Enable
When the STOP option is selected (STOPEN = 1), the STOP
instruction is enabled.
When the STOP option is deselected (STOPEN = 0), the STOP
instruction is equivalent to a WAIT instruction.
IRQ — IRQ sensitivity
When the IRQ option is selected (IRQ = 1), edge- and level-sensitive
IRQ is enabled.
When the IRQ option is deselected (IRQ = 0), edge-only sensitive IRQ
is enabled.
NOTE:
The port B keyscan interrupt sensitivity will match that of the IRQ
information.)
