Using the Peripheral DMA Controller
Interrupts can be disabled by writing a one to the corresponding bit in the Interrupt Disable Reg-
ister (IDR). The interrupt Mask Register (IMR) can be read to check if an interrupt is enabled or
disabled.
To relieve the CPU of data transfers the aWire UART user interface support using the Peripheral
DMA controller.
To transmit using the Peripheral DMA Controller do the following:
To receive using the Peripheral DMA Controller do the following:
1. Setup the aWire UART user interface in transmit mode.
2. Setup the Peripheral DMA Controller with buffer address and length, use byte as trans-
3. Enable the Peripheral DMA Controller.
4. Wait until the Peripheral DMA Controller is done.
