CONFIGURING THE ALARM
In order to configure the alarm modules, the following
steps need to be performed:
1.
Load the timekeeping registers and enable the
oscillator
2.
Configure the ALMxMSK<2:0> bits to select the
desired alarm mask
3.
Set or clear the ALMPOL bit according to the
desired output polarity
4.
Ensure the ALMxIF flag is cleared
5.
Based on the selected alarm mask, load the
alarm match value into the appropriate
register(s)
6.
Enable the alarm module by setting the
ALMxEN bit
