AUDIO OUTPUT
Port C is an 8-bit bi-directional programmable Input / Output port with Pull-high or
Open-drain option. As inputs, Port C can be in either the Pure or Pull-high states. As
outputs Port C can be a Buffer or Open-drain NMOS type (sink current).
IOC1: Can also be selected as an external interrupt PIN
IOC2: EXT COUNT IN
**See note 1 and 2 below.
Port D is an 8-bit bi-directional programmable Input / Output port with Pull-low or
Open-drain option. As inputs, Port D can be either Pure or Pull-low states. As outputs,
Port D can be either Buffer or Open-drain PMOS type (send current). (Port D can be
software programmed for wake up I/O PIN)
