14.1.9.10 TX_DATA
This register is used to fill the FIFO with the data to be transmitted & accessible as write
only registers, if the I2C Master is configured for transmission.
Table 285. TX_DATA (address offset 0x0040 to 0x004C)
Legend: * reset value; <= mandatory value
Bit Symbol
31:0 TX_DATA
1. The TX_DATA register fields are accessible as write-only during I2C master
configured as I2C transmitter. (IP_MODE = 0x0 in CONFIG_REG)
2. The Data written to TX_DATA register fields are considered to be WORD size,
however the byte granularity will be interpreted by the BYTECOUNT_CONFIG_REG
register.
3. The TX_DATA from offset address 0x0040 to 0x004C, is order independent. The TX
data can be written to any of these offset address 0x0040 or 0x0044 or 0x0048 or
0x004C in any order.
14.1.9.11 RX_DATA
This register is used to read the received data from FIFO & accessible as read only
registers if the I2C Master is configured for reception.
