UART_EV_STATUS

Address: 0xf0009000 + 0xc = 0xf000900c

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: 0xf0009000 + 0x10 = 0xf0009010

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 triggered on a falling edge.

[1]

RX

1 if a rx event occurred. This Event is triggered on a falling edge.

UART_EV_ENABLE

Address: 0xf0009000 + 0x14 = 0xf0009014

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
