These eight I/O lines comprise port B. The state of any pin is software
programmable. All port B lines are configured as input during power-on or external
reset.
PB7 is also used as the RSPWM counter reset input when PB7 is set as an input
pin and the counter reset enable bit is set in the GPWM register (bit 6 of $0010).
These eight I/O lines comprise port C. The state of any pin is software
programmable. All port C lines are configured as input during power-on or external
reset.
PC0-PC5 become keyboard interrupt input pins when the corresponding bits are
set in the Keyboard Interrupt register ($001E).
PC6 and PC7 are SDA and SCL respectively, when used for the software
supported M-Bus Interface.
These are the hardware M-Bus interface data and clock lines.
This input pin controls the input capture function of the 16-bit free-running timer.
This output pin indicates when a timer compare is successful.
This is the output pin of the General purpose PWM.
These are the two excursive outputs of the Raster Positioning PWM
This is the input clock to drive the RSPWM counter.
These two input pins are for the video sync signals from the host computer.
This is the Composite sync signal input from the host computer.
This is the output of an sample signal from the Sync Signal Processor.
These are the output from the HSYNC and VSYNC inputs or the signals separated
from CSYNC input.
