Table 2.11.7 lists the functions of the input/output pins during UART mode. Note that for a period from
when the UARTi operation mode is selected to when transfer starts, the TxDi pin outputs a “H”. (If the N-
channel open-drain is selected, this pin is in floating state.)

Function
Serial data output
Method of selection
Serial data input
Port P62 and P71 direction register (bit 2 at address 03EE16,
bit 1 at address 03EF16)= “0”
(Can be used as an input port when performing transmission only)
Programmable input port Internal/external clock select bit (bit 3 at address 03A016, 037816) = “0”
Port P55 and P72 direction register (bit 5 at address 03EB16,
bit 2 at address 03EF16) = “0”
Transfer clock input
Internal/external clock select bit (bit 3 at address 03A016, 037816) = “1”
Port P55 and P72 direction register (bit 5 at address 03EB16,
bit 2 at address 03EF16) = “0”
