Description

FMAC X1 buffer configuration register

Fields

X1_BASE

Base address of X1 buffer

X1_BUF_SIZE

Allocated size of X1 buffer in 16-bit words The minimum buffer size is the number of feed-forward taps in the filter (+ the watermark threshold1).

FULL_WM

Watermark for buffer full flag Defines the threshold for setting the X1 buffer full flag when operating in circular mode. The flag is set if the number of free spaces in the buffer is less than 2FULL_WM. 2: Threshold = 4 3: Threshold = 8 Setting a threshold greater than 1 allows several data to be transferred into the buffer under one interrupt. Threshold should be set to 1 if DMA write requests are enabled (DMAWEN = 1 in FMAC_CR register).

0 (B_0x0): Threshold = 1

1 (B_0x1): Threshold = 2
