Function
Synchronous serial data I/O for I2C interface. Also is the serial programming data line.
This pin can also serve as a general purpose I/O. If enabled, a change on this pin can
cause a CPU interrupt. This pin has an N-channel pull-up to VDD which is disabled in
I2C mode.
Synchronous serial clock for I2C interface. Also is the serial programming clock. This pin
can also serve as a general purpose I/O. If enabled, a change on this pin can cause a
CPU interrupt. This pin has an N-channel pull-up to VDD which is disabled in I2C mode.
B5
RC5
LED direct-drive output. This pin can also serve as a GPIO. If enabled, a change on this
pin can cause a CPU interrupt. If enabled, this pin has a weak internal pull-up to VDD.
B4
RC4
LED direct-drive output. This pin can also serve as a GPIO. If enabled, a change on this
pin can cause a CPU interrupt. If enabled, this pin has a weak internal pull-up to VDD.
B3
RC3/T0CKI LED direct-drive output. This pin can also serve as a GPIO. If enabled, this pin has a
weak internal pull-up to VDD. T0CKI is enabled as TMR0 clock via the OPTION register.
B2
RC2
LED direct-drive output. This pin can also serve as a GPIO. If enabled, this pin has a
weak internal pull-up to VDD.
B1
RC1/CMPA LED direct-drive output. This pin can also serve as a GPIO, or comparator A output. If
enabled, this pin has a weak internal pull-up to VDD.
B0
RC0/REFA LED direct-drive output. This pin can also serve as a GPIO, or programmable reference
A output. If enabled, this pin has a weak internal pull-up to VDD.
U= unimplemented, X = unknown.
