The customer use DMAC transfer for UART.
Can DMACB Transfer width be used both 16bit and 8bit for transfering from transmit data buffer on the RAM to TDR?
Example use case
1)8bit data
Use 8bit DMACB for transfering from 8-bit transmit data buffer on the RAM to TDR.
2)Operation Mode 1 (Asynchronous Multiprocessor Mode)
Use 16bit DMACB for transfering from 16-bit transmit data buffer on the RAM to TDR.

Inoue

Hi,
the TDR register can only be accessed by 16 or 32 bit access (Halfword and Word).
The information can be found in the register map at the end of the TRM.
kind regards,
Achim
