7 RESET_EVENT_A_LEVEL
Read/write
[6:0] RESET_EVENT_A[6:0]
Read/write
Description
Defines which level the first reset event should be to generate the RESET_OUT
signal.
For key events, use the following settings:
0 = inactive event used as a reset condition.
1 = active event used as a reset condition.
For GPIs and logic outputs configured for FIFO updates, use the following settings:
0 = not applicable; releases not used for reset generation.
1 = press is used as a reset event.
Defines an event that can be used to generate the RESET_OUT signal. Up to three
events can be defined for generating the RESET_OUT signal, using
RESET_EVENT_A[6:0], RESET_EVENT_B[6:0], and RESET_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.
