Table 124. RX FIFO Overflow Event ($0x5A0)

Bit	Name	Description	Type1	Default
Register Description: This register provides a status if a FIFO-full situation occurs (for
example, a FIFO overflow). The bit position equals the port number. This register is cleared on				0x00000000
Read.

	Event on Port 3
		1 = FIFO overflow event occurred
	RX FIFO Overflow	Port 2
2		0 = FIFO overflow event did not occur	R	0
	Event on Port 2
		1 = FIFO overflow event occurred
	RX FIFO Overflow	Port 1
1		0 = FIFO overflow event did not occur	R	0
	Event on Port 1
