Fig. 70 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 71, 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.
