The temperature-sensor control register controls the
internal and external temperature measurement.
IMUX<1:0>: Internal current-source MUX bits. Selects
the pin to be driven by the internal current sources as
shown in Table 20. The power-on default is 00.
16-Bit, Data-Acquisition System with ADC, DACs,
UPIOs, RTC, Voltage Monitors, and Temp Sensor
SPDT2<1:0>: Single-pole double-throw switch 2 control
bits. The SPDT2<1:0> bits, the UPIO pins (if config-
ured), and the PWM (if configured) control the state of
the switch as shown in Table 19. The UPIO_ states of 0
and 1 in the table correspond to respective deasserted
and asserted logic states as defined by the ALH_ bit in
the UPIO_CTRL register. If a UPIO is not configured for
TEMP_CTRL Register (Power-On State: 0000 XXXX)

IVAL<1:0>: Internal current-source value bits. Selects
the value of the internal current source as shown in
Table 21. The power-on default is 00.
this mode, its value applied to Table 19 is 0. The PWM
states of 0 and 1 in Table 19 correspond to the respec-
tive PWM off (low) and on (high) states defined by the
SPD2 bit in the PWM_CTRL register. If the PWM is not
configured for this mode, its value applied to Table 19 is
0. The power-on default is 00.
