Clarifications/Corrections to the Data Sheet:
In the Device Data Sheet (DS40189D), the following
clarifications and corrections should be noted.
1. Module: Low Voltage Detector
In Section 2.1.3, Low Voltage Detector, page 6, typical
levels have been adjusted to more accurately reflect
actual device performance. MPLAB
higher will match these modified typical values.
2.1.3
A low battery voltage detector onboard the HCS362
can indicate when the operating voltage drops below a
predetermined value. There are eight options available
depending on the VLOW[0..2] configuration options.
The options provided are:
