6.14 Analog Blocks Enable Control
Various analog circuit blocks can be enabled or
disabled, as shown in Register 6-15. Addition enable
bits are located in the ATSTCON register.
6.14.1 OUTPUT OVERVOLTAGE ENABLE
The output overvoltage is enabled by setting the
ABECON<OVDCEN> bit. Clearing this bit will disable
the output overvoltage circuitry and cause the setting in
the OOVCON register to be ignored.
6.14.2 OUTPUT UNDER VOLTAGE
ENABLE
The output under voltage is enabled by setting the
ABECON<UVDCEN> bit. Clearing this bit will disable
the output under voltage circuitry and cause the setting
in the OUVCON register to be ignored.
6.14.3 RELATIVE EFFICIENCY
MEASUREMENT CONTROL
Section 10.0 “Relative Efficiency Measurement”
describes the procedure used to measure the relative
efficiency of the system. Setting the
ABECON<MEASEN> bit initiates the relative
measurement.
6.14.4 SLOPE COMPENSATION CONTROL
The slope compensation described in Register 6-7 can
be bypassed by setting the ABECON<SLCPBY> bit.
Under normal operation, this bit will always be set.
6.14.5 CURRENT MEASUREMENT
CONTROL
The peak current measurement circuitry is controlled
by the ABECON<CRTMEN> bit. Setting this bit
enables the current measurement circuitry. Under
normal operation, this bit will be set.

6.14.6 INTERNAL TEMPERATURE
MEASUREMENT CONTROL
The internal temperature of the silicon can be
measured with the ADC. To enable the internal
temperature measurement circuitry, the
ABECON<TMPSEN> bit must be set.
6.14.7 RELATIVE EFFICIENCY CIRCUITY
CONTROL
Section 10.0 “Relative Efficiency Measurement”
describes the procedure used to measure the relative
efficiency of the system. Setting the
ABECON<RECIREN> bit enables the relative
efficiency measurement circuitry.
6.14.8 SIGNAL CHAIN CONTROL
Setting the ABECON<PATHEN> bit enables the
voltage control path. Under normal operation, this bit is
set.
