13.2.3
The Comparator Control Register 0 (CMP_CR0) enables
and configures the input range of the comparators.
Bit 4: CMP1EN. This bit enables comparator 1.
13.2.4
The Comparator Control Register 1 (CMP_CR1) config-
ures the comparator output options.
Bit 7: CINT1. This bit connects the comparator 1 output
to the analog output.
Bit 6: CPIN1. This bit selects whether the comparator 1
LUT output or the latched output is routed to a GPIO pin.
Bit 5: CRST1. This bit selects whether the comparator 1
latch is reset upon a register write or by a rising edge from
the comparator 0 LUT output.
Bit 4: CDS1. This bit selects between the comparator 1
LUT and the latched output for the main comparator out-
put that drives to the capacitive sense and interrupt logic.
13.2.5
The Comparator LUT Control Register (CMP_LUT) selects
the logic function.
Bits 7 to 4: LUT1[3:0]. These bits control the selection of
the LUT 1 logic functions that may be selected for the com-
parator channel 1.
Bits 3 to 0: LUT0[3:0]. These bits control the selection of
LUT 0 logic functions that may be selected for the compara-
tor channel 0. The selections are shown in the following
table:
