Description
Defines which level the second reset event should be to generate the RESET2
signal. Refer to Table 52.
Defines an event that can be used to generate the RESET2 signal. Refer to Table 11.
Defines an event that can be used to generate the RESET1 signal. Refer to Table 11.
Defines an event that can be used to generate the RESET1 signal. Refer to Table 11.
Description
Defines which level the first reset event should be to generate the RESET2 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.
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 to generate the RESET1
signal. Refer to Table 49.
Description
Defines which level the second reset event should be to generate the RESET1
signal. Refer to Table 49.
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. This function not
applicable to RESET2.
