Table 31. Alternate Function Enabling
Setting the bits in the Port A-K output control registers (see
specified port pins for open-drain operation. These registers affect the pins directly and as a
result, alternate functions are also affected. Enabling the I
configures the SCL and SDA pins as open-drain; independent of the setting in the output
control registers that have the SCL and SDA alternate functions.
POC[7:0]—Port Output Control
These bits function independently of the alternate function bits and disable the drains
if set to 1.
