Pin name
Table 14.3 lists pin functions for the case where the multiple transfer clock output pin select function is
deselected. Table 14.4 lists the P6
Note that for a period from when the UARTi operation mode is selected to when transfer starts, the TxDi
pin outputs an “H”. (If the N-channel open-drain output is selected, this pin is in a high-impedance state.)
