XE8806A/XE8807A
The cmpd peripheral is a 4-channel low power comparator. It is intended to compare analog input signals with an
internally set threshold voltage. The comparator maintains low current consumption even if the input signal is very
close to the threshold. The comparison result of each channel can be used to generate an interrupt and/or is
available for polling.
The comparator can be enabled or disabled by programming the Enable bit in the RegCmpdCtrl register. When
disabled, the block consumes no current.
The peripheral has a single interrupt output which is a combination of the four channels. The combination can be
chosen by programming the RegCmpdCtrl register. The EnIrqCh[3:0] bits select the channel that can activate the
interrupt. The IrqOnRisingCh[2:0] bits indicate if the interrupt is generated on detection of the rising or falling edge
of the channel.
The comparison results of the peripheral can be read in the RegCmpdStat register. The bits CmpdOut[3:0] are
the value of the comparisons at the moment the register is read. The CmpdStat[3:0] indicates which channel
generated an interrupt since the register was last read.

Comments:
1.
The quiescent current is defined for a static input voltage <0.5V or >1.3V. The specified consumption is the
sum for all 4 channels.
2.
The maximal static current is defined for any static input voltage between VDD and VSS. The specified
consumption is the sum for all 4 channels.
3.
Defined with respect to VSS.
How to start the cmpd:
To avoid unwanted irqs one has first to configure the rising / falling edge of the detection (bit IrqOnRisingCh[2:0])
and to enable the comparator (bit Enable). Only after that may the user enable the channel interrupts with bit
EnIrqCh[3:0].

Register map
There are two registers in the Cmpd, namely RegCmpdStat and RegCmpdCtrl. Table 19-3 and Table 19-4 show
the mapping of the control bits and the functionality of these registers.
