Modes 2 and 3 (EXPE = 0)
In modes 2 and 3 (when EXPE = 0), port 2 pins function as PWM outputs (P27 can also function
as the timer connection output (CBLANK)) or I/O ports, and input or output can be specified on a
bit-by-bit basis. When a bit in P2DDR is set to 1, the corresponding pin functions as a PWM
output or output port, and when cleared to 0, as an input port. P27 can be used as an on-chip
supporting module output pin regardless of the P27DDR setting.
The port 2 pin functions are shown in figure 8.8.
