Section 8 I/O Ports

Rev. 3.00 Jan 18, 2006 page 214 of 1044

REJ09B0280-0300

Modes 2 and 3 (EXPE = 0): In modes 2 and 3 (when EXPE = 0), port 2 pins function as PWM

outputs (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.
