Figure 79
shows the three sources that can control the pin output enable signal:
a product term from AND-OR array; the csiop Direction register; or the Peripheral I/O Mode
logic (Port A only). The csiop Enable Out registers represent the state of the final output
enable signal for each port pin driver, and are defined in
Table 196 on page 242

1. Port A not available on 52-pin UPSD34xx devices.
2. For each bit, 1 = pin drive type is selected, 0 = pin drive type is default mode, CMOS push/pull.
3. Default state for register is 00h after reset or power-up.
