Table 2.11.4 lists the functions of the input/output pins during clock synchronous serial I/O 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.)
Table 2.11.4 Input/output pin functions in clock synchronous serial I/O mode
Pin name
Function
Method of selection
TxDi
(P63, P70)
Serial data output
(Outputs dummy data when performing reception only)
RxDi
(P62, P71)
Serial data input
Port P62 and P71 direction register (bits 2 at address 03EE 16,
bit 1 at address 03EF 16)= “0”
(Can be used as an input port when performing transmission only)
CLKi
(P61, P72)
Transfer clock output
Transfer clock input
Internal/external clock select bit (bit 3 at address 03A0 16, 037816) = “0”
Internal/external clock select bit (bit 3 at address 03A0 16, 037816) = “1”
Port P61 and P72 direction register (bits 1 at address 03EE 16,
bit 2 at address 03EF 16) = “0”
CTSi/RTSi
(P60, P73)
CTS input
CTS/RTS disable bit (bit 4 at address 03A4 16, 037C16) =“0”
CTS/RTS function select bit (bit 2 at addresses 03A4 16, 037C16) = “0”
Port P60 and P73 direction register (bits 0 at address 03EE 16,
bit 3 at address 03EF 16) = “0”
RTS output
CTS/RTS disable bit (bit 4 at address 03A4 16, 037C16) = “0”
CTS/RTS function select bit (bit 2 at address 03A4 16, 037C16) = “1”
