Description
7
RESET1_EVENT_A_LEVEL
Read/write
Defines which level the first reset event should be to generate the
RESET1 signal.
For key events, use the following settings:
0 = not applicable; releases not used for reset generation.
1 = press is used as reset event.
For GPIs and logic outputs configured for FIFO updates, use the
following settings:
0 = inactive event used as reset condition.
1 = active event used as reset condition.
6 to 0
RESET1_EVENT_A[6:0]
Read/write
Defines an event that can be used to generate the RESET1 signal. Up to
three events can be defined for generating the RESET1 signal, using
RESET1_EVENT_A[6:0], RESET1_EVENT_B[6:0], and
RESET1_EVENT_C[6:0]. If one of the registers is 0, that register is not
used for reset generation. All reset events must be detected at the
same time to trigger the reset.
