1.4 Mask Options
The MC68HC05RC18 has a total of 13 mask options, including:
Eight Port B Interrupt Enables (one for each pin)
Port B Pullup Enable
Port B Strong/Weak Pullup Select
IRQ Sensitivity
COP Enable/Disable
STOP Enable/Disable
The following are nonprogrammable options in that they are selected at
the time of code submission when masks are made:
PB7IE — Port B7 Interrupt Enable
This option enables or disables the interrupt generation on port B bit 7.
1 = Enables the interrupt
0 = Disables the interrupt
PB6IE — Port B6 Interrupt Enable
This option enables or disables the interrupt generation on port B bit 6.
1 = Enables the interrupt
0 = Disables the interrupt
PB5IE — Port B5 Interrupt Enable
This option enables or disables the interrupt generation on port B bit 5.
1 = Enables the interrupt
0 = Disables the interrupt
PB4IE — Port B4 Interrupt Enable
This option enables or disables the interrupt generation on port B bit 4.
1 = Enables the interrupt
0 = Disables the interrupt
PB3IE — Port B3 Interrupt Enable
This option enables or disables the interrupt generation on port B bit 3.
1 = Enables the interrupt
0 = Disables the interrupt
