UART_RXTX

Address: 0xf0000000 + 0x0 = 0xf0000000

UART_TXFULL

Address: 0xf0000000 + 0x4 = 0xf0000004

TX FIFO Full.

UART_RXEMPTY

Address: 0xf0000000 + 0x8 = 0xf0000008

RX FIFO Empty.

UART_EV_STATUS

Address: 0xf0000000 + 0xc = 0xf000000c

This register contains the current raw level of the rx event trigger. Writes to this register have no effect.

Field	Name	Description
[0]	TX	Level of the tx event
[1]	RX	Level of the rx event

UART_EV_PENDING

Address: 0xf0000000 + 0x10 = 0xf0000010

When a rx event occurs, the corresponding bit will be set in this register. To clear the Event, set the corresponding bit in this register.

Field	Name	Description
[0]	TX	1 if a tx event occurred. This Event is level triggered when the signal is high.
[1]	RX	1 if a rx event occurred. This Event is level triggered when the signal is high.

UART_EV_ENABLE

Address: 0xf0000000 + 0x14 = 0xf0000014

This register enables the corresponding rx events. Write a 0 to this register to disable individual events.

Field	Name	Description
[0]	TX	Write a 1 to enable the tx Event
[1]	RX	Write a 1 to enable the rx Event

UART_TXEMPTY

Address: 0xf0000000 + 0x18 = 0xf0000018

TX FIFO Empty.

UART_RXFULL

Address: 0xf0000000 + 0x1c = 0xf000001c

RX FIFO Full.
