M16C/29 Group
13.6 I/O Port Function Select
The M16C/29 will automatically configure the port package pins to be IC/OC inputs or outputs based on
the values in the Function Enable (G1FE) and Function Select (G1FS) registers.
When using PWM S-R mode, two channels are enabled and selected as output, but only one output, the
output corresponding to the even numbered channel, is generated.
The port package pin corresponding to the odd numbered channel is available for use as General Pur-
pose Input / Output.
