11.6.4 Register Description
Internal Voltage Reference Register (VREFCR)
Read/Write
Reset Value : 0000 0000 (00h)
Bit 7 = VCEXT External Voltage Reference for
Comparator
This bit is set or cleared by software. It is used to
connect the external reference voltage to the VN
comparator input.
0: External reference voltage not connected to VN
1: External reference voltage connected to VN
Bit 6 = VCBGR Bandgap Voltage for Comparator
This bit is set or cleared by software. It is used to
connect the bandgap voltage of 1.2V to the VN
comparator input.
0: Bandgap voltage not connected to VN
1: Bandgap voltage connected to VN
Bits 5:2 = VR[3:0] Programmable Internal Voltage
Reference Range Selection
These bits are set or cleared by software. They are
used to select one of 16 different voltages availa-
ble from the internal voltage reference module and
connect it to comparator input VN.

Reset Value : 1000 0000 (80h)
Bit 7= CHYST Comparator Hysteresis Enable
This bit is set or cleared by software and set by
hardware reset. When this bit is set, the compara-
tor hysteresis is enabled.
0: Hysteresis disabled
1: Hysteresis enabled
Note: To avoid spurious toggling of the output of
the comparator due to noise on the voltage refer-
ence, it is recommended to enable the hysteresis.
Bit 6 = Reserved, Must be kept cleared
Bit 5 = CINV Comparator Output Inversion Select
This bit is set or cleared by software and cleared
by hardware reset. When this bit is set, the compa-
rator output is inverted.
If interrupt enable bit CMPIE is set in the CMPCR
register, the CINV bit is also used to select which
type of level transition on the comparator output
will generate the interrupt. When this bit is reset,
interrupt will be generated at the rising edge of the
comparator output change (COMP signal, refer to
Figure 62 on page

rator output change (COMP signal, refer to
