1.4 Mask Options
There are 11 total mask options on the MC68HC05RC16 including:
Eight port B pullups
IRQ sensitivity
COP enable/disable
STOP enable/disable
These are nonprogrammable options in that they are selected at the time
of code submission (when masks are made). These options are as
follows:
PB7PU — Port B7 Pullup/Interrupt
This bit enables or disables the pullup/interrupt on port B, bit 7.
1 = Enables the pullup/interrupt
0 = Disables the pullup/interrupt
PB6PU — Port B6 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 6.
1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
PB5PU — Port B5 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 5.
1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
PB4PU — Port B4 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 4.
1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
PB3PU — Port B3 Pullup/Interrupt
This option enables or disables the pullup/interrupt on port B, bit 3.
1 = Enables pullup/interrupt
0 = Disables pullup/interrupt
