5 PERIPHERAL CIRCUITS AND THEIR OPERATION (Serial Interface)
s Data receive procedure
The control procedure and operation during
receiving is as follows.
(1) Write "0" in the receive enable register RXEN to
set the receiving disable status and to reset the
respective PER, OER, FER flags that indicate
parity, overrun and framing errors.
(2) Write "1" in the receive enable register RXEN to
set into the receiving enable status.
(3) The shift clock will change to enable from the
point where the start bit (LOW) has been input
from the SIN terminal and the receive data will
be synchronized to the rising edge following the
second clock, and will thus be successively
incorporated into the shift register.
After data bits have been incorporated, the stop bit
is checked and, if it is not HIGH, it becomes a
framing error and the error interrupt factor flag
FSERR is set to "1". When interrupt has been
enabled, an error interrupt is generated at this point.
When receiving is completed, data in the shift
register is transferred to the received data buffer
and the receiving complete interrupt flag FSREC
is set to "1". When interrupt has been enabled, a
receiving complete interrupt is generated at this
point. (When an overrun error is generated, the
interrupt factor flag FSREC is not set to "1" and a
receiving complete interrupt is not generated.)
If "with parity check" has been selected, a parity
check is executed when data is transferred into
the received data buffer from the shift register
and if a parity error is detected, the error inter-
rupt factor flag is set to "1". When the interrupt
has been enabled, an error interrupt is generated
at this point just as in the framing error men-
tioned above.
(4) Read the received data from TRXD0–TRXD7
using receiving complete interrupt.
(5) Write "1" to the receive control bit RXTRG to
inform that the receive data has been read out.
When the following data is received prior to
writing "1" to RXTRG, it is recognized as an
overrun error and the error interrupt factor flag is
set to "1". When the interrupt has been enabled,
an error interrupt is generated at this point just as
in the framing error and parity error mentioned
above.
(6) Repeat steps (3) to (5) for the number of bytes of
receiving data, and then set the receive disable
status by writing "0" to the receive enable register
RXEN, when the receiving is completed.
