Module Configuration
DMA Handshake Signals
The specific configuration for the PDCA instance is listed in the following tables.
Table 18-6.
Table 18-7.
The table below defines the valid Peripheral Identifiers (PIDs). The direction is specified as
observed from the memory, so RX means transfers from peripheral to memory and TX means
from memory to peripheral.
