T48C862-R4 [Preliminary]
P4xM2, P4xM1 – Port 4x Interrupt mode/direction code
Table 12. Port 4 Control Register
The bi-directional Port 6 is a bitwise 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 Figure 32 on page 37). Two additional multiplexes allow data and port direc-
tion control to be passed over to other internal module (Timer 3). The I/O pin for 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. Figure 32 on page
37 shows the internal interfaces to bi-directional Port 6.
