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

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

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.
