Clock synchronous serial I/O mode
99
Table 1.14.4 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 is not selected. 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.)

Internal/external clock select bit (bit 3 at address 03A016, 03A816) = “0”
Internal/external clock select bit (bit 3 at address 03A016, 03A816) = “1”
Port P61 and P65 direction register (bits 1 and 5 at address 03EE16) = “0”
Port P62 and P66 direction register (bits 2 and 6 at address 03EE16)= “0”
(Can be used as an input port when performing transmission only)
CTS/RTS disable bit (bit 4 at address 03A416, 03AC16) =“0”
CTS/RTS function select bit (bit 2 at address 03A416, 03AC16) = “0”
Port P60 and P64 direction register (bits 0 and 4 at address 03EE16) = “0”
CTS/RTS disable bit (bit 4 at address 03A416, 03AC16) = “0”
CTS/RTS function select bit (bit 2 at address 03A416, 03AC16) = “1”
CTS/RTS disable bit (bit 4 at address 03A416, 03AC16) = “1”

Note: Clock synchronous serial I/O mode cannot be used in UART2.
