Bidirectional 8-bit I/O port, Each bit can be configured as a wake-up input by
configuration option. Software instructions determine if the pin is a CMOS out-
put or Schmitt trigger input. Configuration options determine which pins on this
port have pull-high resistors.
Bidirectional 4-bit I/O port. Each bit can be configured as a wake-up input by
configuration option. Software instructions determine if the pin is a CMOS out-
put or Schmitt trigger input. Configuration options determine which pins on this
port have pull-high resistors. Pins PB0~PB3 are pin-shared with SPI flash
control and I

OSC1, OSC2 are connected to an external RC network or external crystal, de-
termined by configuration option, for the internal system clock. If the RC sys-
tem clock option is selected, pin OSC2 can be used to measure the system
clock at 1/4 frequency.
