0x0

EN_OR

Combine ADC reset with peak detect. When asserted, this bit causes

the ADC reset pulse (Flag Select Option 0) to be logically OR-ed with

one of the peak-detect flags options specified in Register 0x19B or

0x0

RESERVED

0x0

EN_FLAG1

Enable Flag 1.

0x0

0 = Force AGC4 pin low.

1 = Enable selected flag on AGC4 pin (see FLAG1_SEL).

EN_FLAG0

Enable Flag 0.

0x0

0 = Force AGC3 pin low.

1 = Enable selected flag on AGC3 pin (see FLAG0_SEL).

FORCE_GPIO

Force GPIO use. Force one or more of the pins, AGC1 to AGC4, to be used as a GPIO rather than

any other specified use.

0x00

Bit 0: force AGC1 to be used as a GPIO.

Bit 1: force AGC2 to be used as a GPIO.

Bit 2: force AGC3 to be used as a GPIO.

Bit 3: force AGC4 to be used as a GPIO.

FORCE_GPIO_OUT

Force GPIO use as an output. When used in conjunction with FORCE_GPIO, configure

one or more of the pins, AGC1 to AGC4, to be used as a general purpose output or input.

0x00

Bit 0 = 1: use AGC1 as an output.

Bit 0 = 0: use AGC1 as an input.

Bit 1 = 1: use AGC2 as an output.

Bit 1 = 0: use AGC2 as an input.

Bit 2 = 1: use AGC3 as an output.

Bit 2 = 0: use AGC3 as an input.

Bit 3 = 1: use AGC4 as an output.

Bit 3 = 0: use AGC4 as an input.
