FRXPAR informs the system of an extremely imminent system overrun condition. It represents
the numerical SRAM entry (0–511 for a 2K FIFO) to trigger the panic function. If the value in the
Used Entry Count Register in the FIFO is equal to or greater than the value in the panic register,
a panic alert is triggered.
FRXPSR contains the watermark level to be used for exiting the alarm state. If the alarm state is
in effect and the number of valid entries in the FIFO falls to a value less than or equal to the value
in the FRXPSR, the panic condition ends. This register is read/write by software.

110000000 FIFO Receive Panic
The value to trigger the receive panic function, which triggers when the FIFO Receive Used Entry
Count is equal to or greater than the value in the. The panic state turns off if the FIFO Rx Used
Entry Count falls to less than or equal to the value in the FIFO Receive Panic Shutoff Register
(FRXPSR).
