13.6.6.2 Pin Drive Strength Register (PDSR)
The pin drive strength register is read/write. Each bit resets to logic 0 in single chip mode (MCF52211
default) and logic 1 in EzPort and FAST mode. The fields are described in Table 13-9.
Refer to Table 2-1 for details of which PDSR bit controls which pin.
