DATA SHEET S13990EJ2V0DS00
(c) Broadcast reception
Broadcast reception is performed when the broadcast bit is set to 0, and a communication frame with FFH
(general broadcast) or the local station group address specified in the slave address field is received.
Table 4-8 indicates the SLRC return codes for broadcast reception.
Table 4-8 SLRC Return Codes for Broadcast Reception
SLRC
Description
1000
1. Meaning
: Broadcast reception is started.
2. Occurrence condition
:
1 A broadcast frame up to the data-length field was received from the master unit normally.
2 Once the control field has been received, RBF is ready for reception
Note
.
After the data-length field, 1000 is set in SLRC, and three-byte data consisting of a master address,
control bits, and data-length bits is set in RBF.
3. Microcomputer processing
: Three-byte data consisting of a master address, control bits, and data-
length bits can be read from RBF.
1001
1. Meaning
: The broadcast reception buffer is full.
2. Occurrence condition
: This return code is issued when RBF becomes full during data reception as a
slave unit, preventing subsequent reception data from being set in RBF.
3. Microcomputer processing
: If data consisting of one or more bytes is not read from RBF within the
time below, broadcast reception is aborted.
Reception data read time:
Approx. 1570
μ
s (mode 0)
Approx. 390
μ
s (mode 1)
1010
1. Meaning
: Broadcast reception was terminated normally.
2. Occurrence condition
: This return code is issued when as much data as the amount specified in the
data-length field has been received normally in a communication frame. In this case, the SLRE flag of
the FLG register changes from 1 to 0.
3. Microcomputer processing
: Reception data can be read from RBF, and the number of bytes of
broadcast reception data can be read from RDR2.
1011
1. Meaning
: Broadcast reception was aborted.
2. Occurrence condition
: This return code is issued when reception is terminated prior to the reception
of as much data as the amount specified in the data-length field in a communication frame. In this case,
the SLRE flag of the FLG register changes from 1 to 0.
3. Microcomputer processing
: Reception data can be read from RBF, and the number of bytes of
broadcast reception data can be read from RDR2.
Note
