This 8-bit MMR is the I
0xFFFF0910
This 16-bit MMR holds the required number
Description
Reserved.
Set this bit if greater than 256 bytes are
required from the slave.
Clear this bit when reading 256 bytes or less.
These 8 bits hold the number of bytes
required during a slave read sequence,
minus 1. If only a single byte is required,
these bits should be set to 0.

Description
These bits contain the 7-bit address of the
required slave device.
Bit 0 is the read/write bit.

Read
This 8-bit MMR holds the number of bytes
received so far during a read sequence with a
slave device.
I2CADR0
0xFFFF0918
0x00
Read/write
This 8-bit MMR holds the 7-bit slave address +
the read/write bit when the master begins
communicating with a slave.
When this bit = 1, a read sequence is
requested.
When this bit = 0, a write sequence is
requested.
Description
These bits must be set to [11110b] {hex?}in
10-bit address mode.
These bits contain ADDR[9:8] in 10-bit
addressing mode.
Read/Write Bit.
When this bit = 1, a read sequence is
requested.
When this bit = 0, a write sequence is
requested.
