• PID: Peripheral Identifier
The Peripheral Identifier selects which peripheral should be connected to the DMA channel. Writing a PID will select both which 
handshake interface to use, the direction of the transfer and also the address of the Receive/Transfer Holding Register for the 
peripheral. See the Module Configuration section of PDCA for details. The width of the PID field is device specific and 
dependent on the number of peripheral modules in the device.
