FRM_HRTHRSH0[9:0]
Indicates the Threshold Levels for the Rx FIFOs.
When a channel is enabled and its FIFO count incre-
ments to this value, its FRM_HRTHRSH (
Table 455 on
page 314
) status bit is set. FRM_HRTHRSH0 or
FRM_HRTHRSH1 is selected on a per-channel basis
with the FRM_RTHRSEL (
Table 454 on page 313
)
parameter.
