Specifications REV. G
Specifications in this manual are tentative and subject to change
UART0 to UART2
Figure 1.80: Serial I/O-related registers (5)
1.2.23.1 Clock synchronous serial I/O mode
The clock synchronous serial I/O mode uses a transfer clock to transmit and receive data. Figure 1.81
shows the UARTi transmit/receive mode register. Table 1.25 lists the specifications of the clock syn-
chronous serial I/O mode.

Note: When using multiple pins to output the transfer clock, the following requirements must be met:
UART1 internal/external clock select bit (bit 3 at address 03A8 16) = “0”.
