I2CALT
0xFFFF0938
0x00
Read/write
This 8-bit MMR is used with hardware general
calls when I2CSCON bit 3 is set to 1. This
register is used in cases where a master is
unable to generate an address for a slave, and
instead, the slave must generate the address for
the master.

minus or “to”?}
0xFFFF0940 = I2CID1

0x00
Read/write
These 8-bit MMRs are programmed with I
bus IDs of the slave. See the I2C Bus Addresses
section for further details.
