To generate this transfer:
Setting CMDR.TENBIT enables 10-bit addressing in hardware. Performing transfers with 10-bit
addressing is similar to transfers with 7-bit addresses, except that bits 10:7 of CMDR.ADR must
be set appropriately.
In
driven by the master, the white boxes are driven by the slave.
To perform a master transmitter transfer,
0
When using master receiver mode with 10-bit addressing, CMDR.REPSAME must also be con-
trolled. CMDR.REPSAME must be written to one when the address phase of the transfer should
consist of only 1 address byte (the 11110xx byte) and not 2 address bytes. The I²C standard
specifies that such addressing is required when addressing a slave for reads using 10-bit
addressing.
To perform a master receiver transfer,
1. Program CMDR with START=1, STOP=0, DADR, NBYTES=2 and READ=1.
2. Program NCMDR with START=1, STOP=1, DADR, NBYTES=2 and READ=0.
3. Wait until SR.RXRDY==1, then read first data byte received from RHR.
4. Wait until SR.RXRDY==1, then read second data byte received from RHR.
5. Wait until SR.TXRDY==1, then write first data byte to transfer to THR.
6. Wait until SR.TXRDY==1, then write second data byte to transfer to THR.
1. Program CMDR with TENBIT=1, REPSAME=0, READ=0, START=1, STOP=1 and the
