I2C Master Receive, I2CMRX, Register
Name:
I2CMRX
Address:
0xFFFF0908
Default value: 0x00
Access:
Read only
Function:
This 8-bit MMR is the I2C master receive
register.
I2C Master Transmit, I2CMTX, Register
Name:
I2CMTX
Address:
0xFFFF090C
Default value: 0x00
Access:
Write only
Function:
This 8-bit MMR is the I2C master transmit
register.
I2C Master Read Count, I2CMCNT0, Register
Name:
I2CMCNT0
Address:
0xFFFF0910
Default value: 0x0000
Access:
Read and write
Function:
This 16-bit MMR holds the required number
of bytes when the master begins a read
sequence from a slave device.
Table 99. I2CMCNT0 MMR Bit Designations
Bit
Name
Description
15:9
Reserved.
8
I2CRECNT
Set this bit if more than 256 bytes are
required from the slave.
Clear this bit when reading 256 bytes or
fewer.
7:0
I2CRCNT
These eight bits hold the number of bytes
required during a slave read sequence,
minus 1. If only a single byte is required, set
these bits to 0.
I2C Master Current Read Count, I2CMCNT1, Register
Name:
I2CMCNT1
Address:
0xFFFF0914
Default value: 0x00
Access:
Read only
Function:
This 8-bit MMR holds the number of bytes
received so far during a read sequence with a
slave device.
I2C Address 0, I2CADR0, Register
Name:
I2CADR0
Address:
0xFFFF0918
Default value: 0x00
Access:
Read and write
Function:
This 8-bit MMR holds the 7-bit slave address
and the read/write bit when the master begins
communicating with a slave.
Table 100. I2CADR0 MMR in 7-Bit Address Mode
Bit
Name
Description
7:1
I2CADR
These bits contain the 7-bit address of the
required slave device.
0
R/W
Bit 0 is the read/write bit.
When this bit = 1, a read sequence is requested.
When this bit = 0, a write sequence is requested.

Bit
Name
Description
7:3
These bits must be set to [11110b] in 10-bit
address mode.
2:1
I2CMADR
These bits contain ADDR[9:8] in 10-bit
addressing mode.
0
R/W
Read/write bit.
When this bit = 1, a read sequence is
requested.
When this bit = 0, a write sequence is
requested.
