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.
Latches high signal at high level, clear
on read
Latches high signal at low-level, clear
on read
Latches high signal at high level,
register cleared with written mask
Latches high signal at low-level,
register cleared on read
Differentiates the input signal (low-
>high) register cleared on read
Differentiates the input signal (high-
>low) register cleared on read
Differentiates the input signal (high-
>low) register cleared with written mask
Differentiates the input signal (low-
>high) register cleared with written
mask
Enables the interrupt source for
interrupt generation
rw register, value is latched after first
clock cycle after reset
Register is used as input for the hw, the
register will be cleared due to a HW
mechanism.
