Port 4 Control Register
The bi-directional Port 6 is a bit-wise configurable I/O port and provides the external pins for the
Timer 3. As a normal port, it performs in exactly the same way as bi-directional Port 6 (see
ure 6-6 on page
passed over to other internal modules (Timer 3). The I/O pin for the T3I line has an additional
mode to generate a Timer 3-interrupt. All two Port 6 pins can be individually switched by the
P6CR register.
