CONFIG_RWB
BUSY
The CONFIG_RWB register allows the indirect addressing method to specify whether a read
or write is being performed. A value of ‘1’ means that a read is to be performed on the data
for PHY_ADDR and will be placed in the BURST_SIZE register. A value of ‘0’ means that a
write of the information in BURST_SIZE will be performed for PHY channel address
PHY_ADDR.
The BUSY bit is used in indirect addressing to indicate that a read or write operation is
currently being executed. A value of ‘1’ means the operation is in progress and the
microprocessor should wait. A value of ‘0’ means the operation is finished and the
microprocessor may proceed with further accesses.
