23.9.4 LCM_DMA transfer total byte register (DMA_LCM_AMT)

Symbol

Address

DMA_LCM_AMT

FA73H

DMA_LCM_AMT: Set the number of bytes that need to be read and written.

Note: The actual number of bytes read and written is (DMA_LCM_AMT+1), that is, when

DMA_LCM_AMT is set to 0, 1 byte is transferred, and when DMA_LCM_AMT is set to 255, 256 bytes are

transferred.

23.9.5 LCM_DMA transfer complete byte register (DMA_LCM_DONE)

Symbol

Address

DMA_LCM_DONE

FA74H

DMA_LCM_DONE: The number of bytes that have been transferred so far.

23.9.6 LCM_DMA Send Address Registers (DMA_LCM_TXAx)

Symbol

Address

DMA_LCM_TXAH

FA75H

ADDR[15:8]

DMA_LCM_TXAL

FA76H

ADDR[7:0]

DMA_LCM_TXA: Set the source address of automatic data transmission. Data is read from this address when

performing an LCM_DMA operation.

23.9.7 LCM_DMA Receive Address Registers (DMA_LCM_RXAx)

Symbol

Address

DMA_LCM_RXAH

FA77H

ADDR[15:8]

DMA_LCM_RXAL

FA78H

ADDR[7:0]

DMA_LCM_RXA: Set the target address for data transfer. Data is written from this address when performing an

LCM_DMA operation.
