I/O
Canbesoftwareoptionedasabidirectionalinput/outputorserialinterfaceslaveselectsignal.
PC5/SDI
I/O or O
Can be software optioned as a bidirectional input/output or serial data input.
PC4/SDO
I/O or O
Can be software optioned as a bidirectional input/output or serial data output.
PC3
I/O
Bidirectional I/O lines. Software instructions determine if the pin is a CMOS output or a
Schmitttriggerinput.Pull-highresistorcanbeconnectedtothepinsviaconfigurationoptions.
PC2/TMR1,
PC1/TMR0
I/O
Software instructions determine if the pin is a CMOS output or a Schmitt trigger input.
Pull-high resistor can be connected to the pins via configuration options.TMR0, TMR1 are
pin shared with PC1, PC2 respectively.
PC0/BZ
I/O or O
Can be software optioned as a bidirectional input/output or as a PFD output.
OSCI
