27.2 Voltage Comparator Registers
VCEn
(1)
The Voltage Comparator is controlled by means of the following registers:
Voltage Comparator registers overview
Base addresses of Voltage Comparator instances
VCCTLn - Voltage Comparator n control register
The 8-bit VCCTLn register controls whether the Voltage Comparator is
operating or is in stand-by mode. Further it specifies whether an interrupt is
generated when V
transitions.
This register can be read/written in 8-bit or 1-bit units.
