Description

The receive and transmit FIFOs can be read or written as 32-bit wide registers. The FIFOs contain 32 entries on 32 sequential addresses. This allows the CPU to use its load and store multiple operands to read from/write to the FIFO.

Fields

IDMAEN

IDMA enable This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0).
IDMABMODE

Buffer mode selection. This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0).
IDMABACT

Double buffer mode active buffer indication This bit can only be written by firmware when DPSM is inactive (DPSMACT = 0). When IDMA is enabled this bit is toggled by hardware.
