Top of list Index page HAL Stop DMA Transfer Interrupt 0xA1 service 0xB1: HAL: Stop DMA Transfer Parameters AH AL Disables the DMA controller. A running DMA transfer will be halted. Must be 0xB1 DMA channel: 0 = DRQ0 1 = DRQ1 Return Value Comments Success: AX = 0 AX = -1 Invalid DMA channel AX = -2 DMA channel used for serial interface Stops a DMA transfer (disables the DMA controller). The transfer could be continued by reading the current DMA values (using function Get DMA Info) and starting the DMA Transfer again with the read values (using function Start DMA Mode) Related Topics Top of list Index page Start DMA Transfer Interrupt 0xA1 service 0xB2: HAL: Get DMA Info Parameters AH AL Get the state of the DMA channel.
