I2C Slave Receive Registers
Name:
I2C0SRX, I2C1SRX
Address:
0xFFFF0830, 0xFFFF0930
Default Value:
0x00
Access:
Read
Function:
This 8-bit MMR is the I2C slave receive register.
I2C Slave Transmit Registers
Name:
I2C0STX, I2C1STX
Address:
0xFFFF0834, 0xFFFF0934
Default Value:
0x00
Access:
Write
Function:
This 8-bit MMR is the I2C slave transmit register.
I2C Hardware General Call Recognition Registers
Name:
I2C0ALT, I2C1ALT
Address:
0xFFFF0838, 0xFFFF0938
Default Value:
0x00
Access:
Read/write
Function:
This 8-bit MMR is used with hardware general
calls when I2CxSCON 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.
I2C Slave Device ID Registers
Name:
I2C0IDx, I2C1IDx
Addresses:
0xFFFF093C = I2C1ID0
0xFFFF083C = I2C0ID0
0xFFFF0940 = I2C1ID1
0xFFFF0840 = I2C0ID1
0xFFFF0944 = I2C1ID2
0xFFFF0844 = I2C0ID2
0xFFFF0948 = I2C1ID3
0xFFFF0848 = I2C0ID3
Default Value:
0x00
Access:
Read/write
Function:
These 8-bit MMRs are programmed with I2C
bus IDs of the slave. See the I2C Bus Addresses
section for further details.
I2C Common Registers
I2C FIFO Status Register
Name:
I2C0FSTA, I2C1FSTA
Address:
0xFFFF084C, 0xFFFF094C
Default Value:
0x0000
Access:
Read/write
Function:
These 16-bit MMRs contain the status of the
Rx/Tx FIFOs in both master and slave modes.

[00] = FIFO empty.
[01] = byte written to FIFO.
[10] = one byte in FIFO.
[11] = FIFO full.
[1:0]
I2CSTXSTA
I2C slave transmit FIFO status bits.
[00] = FIFO empty.
[01] = byte written to FIFO.
[10] = one byte in FIFO.
[11] = FIFO full.
