Data Sheet
Description
Must be ’000’.
External interrupt enable
’0’ = normal operation
’1’ = external interrupt from GPI24 . . . GPI31
enable (These pins must be connected to a pull-up
resistor to VDD. Any low input signal on one of the
lines will generate an external interrupt.)
Output buffer configuration for pin PWM0
’00’ =PWM output tristate (disable)
’01’ = PWM push / pull output
’10’ = PWM push to 0 only
’11’ = PWM pull to 1 only
Output buffer configuration for pin PWM1
’00’ = PWM output tristate (disable)
’01’ = PWM push / pull output
’10’ = PWM push to 0 only
’11’ = PWM pull to 1 only
