Table 11. Setting the Signal-Detect
Comparator Threshold
X = Don’t care.
The REF_SDC register contains bits to control the refer-
ence voltage and signal-detect comparator.
REFV<1:0>: Reference buffer voltage gain and enable
bits. Enables the output buffer, and sets the gain and
the voltage at the REF pin as shown in Table 10. Power-
on state is off to enable an external reference to drive
the REF pin without contention.
AOFF: ADC and DAC/op-amp power-off bit. This bit pro-
vides a method for turning off several analog functions
with a single write. Setting AOFF = 1 deasserts the
ADCE in the ADC register and the DAE, DBE, and OP1E
bits in the DACA_OP and DACB_OP registers, powering
down these analog blocks. Setting AOFF = 0 has no
effect. The AON bit has priority when both AON and
AOFF bits are asserted.
Most of the analog functions can be disabled with a
single write to the REF_SDC register by using AOFF,
REFV<1:0>, and SDCE.
AON: ADC and DAC/op-amp power-on bit. This bit pro-
vides a method of turning on several analog functions
with a single write. Setting AON = 1 asserts the ADCE
bit in the ADC register and DAE, DBE, and OP1E bits in
the DACA_OP and DACB_OP register, powering up
these blocks. Setting AON = 0 has no effect. The AON
bit has priority when both AON and AOFF bits are
asserted.
Most of the analog functions can be enabled with a sin-
gle write to the REF_SDC register using AON,
REFV<1:0>, and SDCE.
SDCE: Signal-detect comparator power-enable bit. Set
SDCE = 1 to power up the signal-detect comparator,
and set SDCE = 0 to power down the signal-detect
comparator. The ADCE bit in the ADC register must be
set to 1 to use the signal-detect comparator.
TSEL<2:0>: Threshold-select bits. These bits select the
threshold for the signal-detect comparator as shown in
Table 11.
