R262406 (0x40106)
MIF1_CONFIG_4
20:0 MIF1_TX_
LENGTH[20:0]
0x00_
0000
Selects the total number of data bytes in an I2C Write operation.
0x00_0000 = 1 byte
0x00_0001 = 2 bytes
0x00_0002 = 3 bytes
0x1F_FFFF = 2,097,152 bytes
R262416 (0x40110)
MIF1_CONFIG_5
20:0 MIF1_RX_
LENGTH[20:0]
0x00_
0000
Selects the total number of data bytes in an I2C Read operation.
0x00_0000 = 1 byte
0x00_0001 = 2 bytes
0x00_0002 = 3 bytes
0x1F_FFFF = 2,097,152 bytes
R262418 (0x40112)
MIF1_CONFIG_6
7:0 MIF1_TX_BLOCK_
LENGTH[7:0]
0x10
Selects the interval at which the MIF1_BLOCK Interrupt is triggered
during I2C Write operations.
0x00 = 1 byte
0x01 = 1 byte
0x02 = 2 bytes
0x10 = 16 bytes
All other codes are reserved
R262420 (0x40114)
MIF1_CONFIG_7
7:0 MIF1_RX_BLOCK_
LENGTH[7:0]
0x10
Selects the interval at which the MIF1_BLOCK Interrupt is triggered
during I2C Read operations.
0x00 = 1 byte
0x01 = 1 byte
0x02 = 2 bytes
0x10 = 16 bytes
All other codes are reserved
R262422 (0x40116)
MIF1_CONFIG_8
4
MIF1_RX_DONE
0
RX Buffer access control bit. Write 1 to indicate that data in the RX
Buffer has been read.
In normal operation, a 1 is written after reading the RX buffer. This
causes the MIF1_RX_REQUEST bit to be cleared. (Note that, if further
data is available to read, the MIF1_RX_REQUEST bit remains set in this
case.)
0
MIF1_TX_DONE
0
TX Buffer access control bit. Write 1 to indicate the TX Buffer has been
filled with data for transmission.
In normal operation, a 1 is written after writing the TX buffer. This causes
the MIF1_TX_REQUEST bit to be cleared.
R262528 (0x40180)
MIF1_STATUS_1
8
MIF1_BUSY_STS
0
MIF Busy Status.
This bit, when set, indicates that the master interface is executing an I2C
transaction.
8
MIF1_RX_REQUEST
0
RX Buffer flow control bit
0 = No data available to read
1 = Buffer data is available to read
1
MIF1_TX_REQUEST
0
TX Buffer flow control bit
0 = TX buffer not available to write
1 = TX buffer is available to write
R262530 (0x40182)
MIF1_STATUS_2
20:0 MIF1_BYTE_
COUNT[20:0]
0x00_
0000
Number of data bytes transferred in current transaction.
Note that this field is cleared on completion of the I2C transaction.
R262656 (0x40200)
MIF1_TX_1
