C Master Transmit Data Register

This register contains the data to be written (transmitted) to an external slave when a write operation is
initiated using the

C Master Control Register”

. This register should be written with data to be sent

prior to setting the START bit in that register.

As bytes are written to the I

2

C bus, they are taken from this register depending on DORDER in the

C Master Configuration Register”

. If DORDER is 0, bytes are taken from MSB to LSB, in order:

TBYTE3, TBYTE2, TBYTE1, TBYTE0. If DORDER is 1, bytes are taken from LSB to MSB, in
order: TBYTE0, TBYTE1, TBYTE2, TBYTE3. If the transaction size is less than 4 bytes (that is, SIZE
in the

C Master Control Register”

<4) then any remaining bytes in the register are unused. The

contents of this register are not affected by the transaction.

Register name: I2C_MST_TDATA

Reset value: 0x0000_0000

Register offset: 0x1D114
