Description
Defines which level the third reset event should be.
Defines an event that can be used to generate the RESET1 signal.
Description
Defines which level the first reset event should be.
For key events:
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:
0 = inactive event used as reset condition.
1 = active event used as reset condition.
Defines an event that can be used to generate the RESET2 signal.
Up to two events can be defined for generating the RESET2 signal, using
RESET2_EVENT_A[6:0] and RESET2_EVENT_B[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.
Description
Defines which level the second reset event should be.
Defines an event that can be used to generate the RESET2 signal.
Description
Sets the polarity of RESET2.
0 = RESET2 is active low.
1 = RESET2 is active high.
Sets the polarity of RESET1.
0 = RESET1 is active low.
1 = RESET1 is active high.
Allows the RST pin to override (OR with) the RESET1signal.
Function not applicable to RESET2.
Defines the length of time that the reset events must be active before a reset signal is
generated.
All events must be active at the same time for the same duration. Parameter common
to both RESET1 and RESET2.
000 = immediate.
001 = 1.0 sec.
010 = 1.5 sec.
011 = 2.0 sec.
100 = 2.5 sec.
101 = 3.0 sec.
110 = 3.5 sec.
111 = 4.0 sec.
