7.5.2 Port B PWM Channel
7.5.3 I/O Configuration Register
MC68HC(8)05PV8/A — Rev. 1.9
The port pin PB4 is shared with the PWM channel. In order to connect
this pin to the PWM channel, the corresponding bit PWM4 of the I/O
configuration register must be set.
TXOR – Timer EXOR Enable
OPAMP – Enable Operational Amplifier
PB4PW – PB4 PWM Enable
PB3OC – PB3 Output Compare Enable
Reset:
$0021
Read:
Write:
This bit enables the EXOR of the TCAP1 channel
This bit enables the operational amplifier on PA6
This bit enables the PB4 pin as PWM output.
This bit enables the PB3 pin for output compare channel 2.
