Figure 7-13 Port 20 IO and Alternate Functions
The port structure of the Port 20 pins depends on their alternate function (see
Figure 7-14).
Note: Enabling the CLKOUT function automatically enables the P20.8 output driver.
Setting bit DP20.8 = ‘1’ is not required.
The CLKOUT function is automatically enabled in emulation mode.
