At completion of transmission by the message buffer (x), the corresponding TCx
becomes 1.
If TIEx of the transmission complete interrupt enable register (TIER) is 1, an interrupt
occurs.

Register Function

Conditions for TCx = 0

Write 0 to TCx.

Write 1 to TREQx of the transmission request register (TREQR).

After the completion of transmission, write 0 to TCx to set it to 0. Writing 1 to TCx is ignored.

1 is read when a Read Modify Write instruction is performed.

Note:

If setting to 1 by completion of the transmit operation and clearing to 0 by writing occur at the same

time, the bit is set to 1.
