General Description
Mask Options
1.3 Ma sk Op tions
The MC68HC05CT4 has eight mask options:
• Six port C pullups
• The IRQ sensitivity
• COP enable/disable
These are nonprogrammable options in that they are selected at the time
of code submission when masks are made. These options are:
PC7PU — Port C7 Pullup
This bit enables or disables the pullup on port C bit 7.
1 = Enables the pullup
0 = Disables the pullup
NOTE: Since port C bit 7 also is shared with the PWM output, PC7PU cannot be
selected if PWM output is needed.
PC6PU — Port C6 Pullup
This option enables or disables the pullup on port C bit 6.
1 = Enables pullup
0 = Disables pullup
PC5PU — Port C5 Pullup
This option enables or disables the pullup on port C bit 5.
1 = Enables pullup
0 = Disables pullup
PC4PU — Port C4 Pullup
This option enables or disables the pullup on port C bit 4.
1 = Enables pullup
0 = Disables pullup
PC23PU — Port C Bits 2 and 3 Pullups
When PC23PU = 1, the pullups on port C bits 2 and 3 are enabled
simultaneously.
When PC23PU = 0, the pullups on port C bits 2 and 3 are disabled
simultaneously.
