Fig. 60 Clock synchronous serial I/O timing
Interrupt request at completion of reception
When the RIk flag changes from “0” to “1”, in other words, when the
receive operation is completed, the interrupt request bit of the
UARTk receive interrupt control register can be set to “1”.
The timing when this interrupt request bit is to be set to “1” can be
selected from the following:
Each reception
When an error occurs at reception
If bit 5 of the UARTk transmit/receive control register 0 (UART re-
ceive interrupt mode select bit) is cleared to “0”, the interrupt request
bit is set to “1” at each reception. If bit 5 is set to “1”, the interrupt re-
quest bit is set to “1” only when an error occurs. (In the clock syn-
chronous serial communication, only when an overrun error occurs,
the interrupt request bit is set to “1”.)
Polarity of transfer clock
In the clock synchronous serial communication, by bit 6 of the UARTj
transmit/receive control register 0 (CPL), the polarity of a transfer
clock can be selected.
As shown in Figure 61, when bit 6 = “0”, the polarity is as follows:
In transmission, transmit data is output at the falling edge of CLKj.
In reception, receive data is input at the rising edge of CLKk.
When not in transfer, CLKi is at “H” level.
When bit 6 = “1”, the polarity is as follows:
In transmission, transmit data is output at the rising edge of CLKj.
In reception, receive data is input at the rising edge of CLKk.
When not in transfer, CLKi is at “L” level.
