base address

EVENTLOGn_CONTR

EVENTLOGn_RST

Event Log Reset

Write ‘1’ to Reset the status outputs

and clear the FIFO buffer.

EVENTLOGn_ENA

EVENTLOGn_TIMER_SEL

[1:0]

Event Log Timer Source Select

00 = Timer 1

01 = Timer 2

EVENTLOGn_FIFO_WMAR

K [3:0]

Event Log FIFO Watermark

The Watermark status output is

asserted when the number of FIFO

locations available for new events is

less than or equal to the FIFO

Watermark.

Valid from 0 to 15.

base address +0Eh

EVENTLOGn_FIFO_P

OINTER1

EVENTLOGn_FULL

Event Log FIFO Full Status

This bit, when set, indicates that the

FIFO buffer is full. It is cleared when a

new value is written to the FIFO Read

Pointer, or when the Event Log is

Reset.

EVENTLOGn_WMARK_ST

Event Log FIFO Watermark Status

This bit, when set, indicates that the

FIFO space available for new events

to be logged is less than or equal to

the Watermark threshold.

EVENTLOGn_NOT_EMPTY

Event Log FIFO Not Empty Status

This bit, when set, indicates one or

more new sets of logged event data in

the FIFO.

11:8

EVENTLOGn_FIFO_WPTR

[3:0]

Event Log FIFO Write Pointer

Indicates the FIFO index location in

which the next event will be logged.

This is a read-only field.

3:0

EVENTLOGn_FIFO_RPTR

[3:0]

Event Log FIFO Read Pointer

Indicates the FIFO index location of

the first set of unread data, if any

exists. For the intended FIFO

behaviour, this field must be

incremented after the respective data

has been read.

base address +20h

EVENTLOGn_CH_ENA

BLE

EVENTLOGn_CH16_ENA

Event Log Channel 16 Enable

0 = Disabled
