6.1 APOOL8

APOOL Module

Category

Functional

Function

APOOL Comparator output edge may not be detected

Description

If the APOOL uses the Digital Filtering feature, after each reconfiguration of the the APCTL and APCNF registers, the Comparator output edge will not be correctly detected.

Workaround

1. After any new configuration of APCTL or APCNF register,
always execute a 'dummy write' instruction to APCTL (or low byte APCNF) which triggers a 'Reset of Deglitch filter' event. (e.g. 'bis' to read-only LCMP bit: bis.w #0010h,&APCNF)
2. Disable the Digital Filter by reseting DFSETx bits.

For detailed workaround guidance,  refer to MSP430x09x Analog Pool: Feature Set and Advanced Use.
