Register is used as input for the HW
Register is written by HW (register
between input and output -> one cycle
delay)
Register is set by HW (register between
input and output -> one cycle delay)
Physically, there is no new register, the
input of the signal is connected directly
to the address multiplexer.
Latch high signal at high level, clear on
read
Latch high signal at low-level, clear on
read
Latch high signal at high level, register
cleared with written mask
Latch high signal at low-level, register
cleared on read
Differentiate the input signal (low-
>high) register cleared on read
Differentiate the input signal (high-
>low) register cleared on read
Differentiate the input signal (high-
>low) register cleared with written mask
Differentiate the input signal (low-
>high) register cleared with written
mask
Enables the interrupt source for
interrupt generation

Description SW
Register is read and writable by SW
Value written by software is ignored by
hardware; that is, software may write any
value to this field without affecting hardware
behavior (= Target for development.)
