Change Status Register

The Change Status Register gives the status of change detection.

Address Offset:

0x02

Type:

Read

Size:

8-bit

Description

7–6

Reserved

Disregard these bits.

WDT Int Status

A 1 indicates that there has been a watchdog timer
expiration that could cause an interrupt (if
watchdog timer expiration interrupts are enabled).

Falling Edge Status

A 1 indicates that there has been a falling edge that
could cause an interrupt (if falling edge interrupts
are enabled).

Rising Edge Status

A 1 indicates that there has been a rising edge that
could cause an interrupt (if rising edge interrupts
are enabled).

MasterInterrupt Status

Indicates that the device is asserting an interrupt.

OverFlow

Indicates that at least one more edge has been
detected since an interrupt is asserted.

Edge Status

Indicates an edge has been detected. If the EdgeInt
bit is set in the Master Interrupt Control Register,
Edge Status set indicates an interrupt is currently
being asserted.
