こんにちは、NXPさん。
ターゲットMCU:S32K388
私はeDMAを使用したSPI伝送に、バーストレジスタTCBRおよびTDBR0-127を使用しています。
現在のフレームサイズは32ビットで、すべて期待どおりに動作しています。
さて、32ビット未満のSPIフレームサイズの場合、DMA転送サイズを変更せずにバーストレジスタをどのように使えるでしょうか。
TCBRは16ビットまたは8ビット単位で書くことができますか?
TDBRnは16ビットまたは8ビット単位で書けますか?
もしなければ、16ビットと8ビットのフレームサイズのDMAチャネルの設定方法についてヒントを教えてもらえますか?
前もって感謝します
