tmp19a43fzxbg TOSHIBA Semiconductor CORPORATION, tmp19a43fzxbg Datasheet - Page 164

• Manufacturer Part Number: tmp19a43fzxbg
• Description: 32bit Tx System Risc
• Manufacturer: TOSHIBA Semiconductor CORPORATION

Example: DMA transfer of serially received data (SCnBUF) to internal RAM
Example DMA settings
Example serial channel settings
DMA (channel 0) is used for transfer. DMA0 is activated by an interrupt received on SIO1.
DMA0 settings
SIO channel 1 settings
• Channel used: 0
• Source address: SC1BUF
• Destination: 0xFFFF_9800 (physical address)
• Number of bytes transferred: 256
• Data length: 8 bits, UART
• Serial channel: Channel 1
• Transfer rate: 9600 bps
