Spi transmission using burst registers

Hello NXP,

Target uC : S32K388

I am using the burst registers TCBR and TDBR0-127 for SPI transmissions using eDMA.

Current frame size is 32 bits and everything works as expected

Now for an SPI frame size which is less than 32 bits, how can the burst registers be used without changing the dma transfer size, in between.

Can TCBR be written in 16 or 8 bit units.

Can TDBRn be written in 16 or 8 bit units

If not, could you give hints as to how to setup the dma channel for frame sizes 16 and 8 bits.

Thanks in advance
