PIN DESCRIPTION AND I/O PORTS

2.3
INPUT/OUTPUT PORTS
In the User Mode there are 24 bidirectional I/O lines arranged as 4 I/O ports (Port A, B, C, and D).
The individual bits in these ports are programmable as either inputs or outputs under software
control by the data direction registers (DDRs). Also, if enabled by software, Port C and D will have
additional functions as PWM outputs, M-Bus I/O and Sync Signal Processor outputs.
2.3.1
Port A
Port A is an 8-bit bidirectional port which does not share any of its pins with other subsystems.
The Port A data register is at $00 and the data direction register (DDR) is at $04. Reset does not
affect the data register, yet clears the data direction register, thereby returning the ports to inputs.
Writing a one to a DDR bit sets the corresponding port bit to output mode.
2.3.2
Port B
Port B is a 6-bit bidirectional port which does not share any of its pins with other subsystems. PB2
to PB5 are +10V open-drain port pins. The Port B data register is at $01 and the data direction
register (DDR) is at $05. Reset does not affect the data register, yet clears the data direction
register, thereby returning the ports to inputs. Writing a one to a DDR bit sets the corresponding
port bit to output mode.
