Specifications REV. G
Specifications in this manual are tentative and subject to change
UART0 to UART2
Table 1.26 lists the functions of the input/output pins during clock synchronous serial I/O mode. This
table shows the pin functions when the transfer clock output from multiple pins function is not selected.
Note that for a period from when the UARTi operation mode is selected to when transfer starts, the
TxD pin outputs a “H”. The typical clock synchronous timing diagrams are shown in Figure 1.82.
Table 1.26:
IART mode input/output pin functions
Pin name
Function
Method of selection
TxDi
(P63, P67, P70)
Serial data
output
(Outputs dummy data when performing reception only)
RxDi
(P62, P66, P71)
Serial data input
Port P62, P66, and P71 direction register (bits 2 and 6 at address 03EE16 bit 1 at address

03EF16) = “0”
CTSi/RTSi
(P60,P64,P73)
CTS input
CTS/RTS disable bit (bit 4 at address 03A416, 03AC16, 037C16) = “0”
CTS/RTS function select bit (bit 2 at address 03A416, 03AC16, 037C16) = “0”
Port P60, P64 and P73 direction register (bits 0 and 4 at address 03EE16, bit 3 at address
03EF16) = “0”
RTS output
CTS/RTS disable bit (bit 4 at address 03A416, 03AC16, 037C16) = “0”
CTS/RTS function select bit (bit 2 at address 03A416, 03AC16, 037C16) = “1”
Programmable I/
O port
CTS/RTS disable bit (bit 4 at address 03A416, 03AC16, 037C16) = “1”
