7
REG_FAIL_CNT_0
REG_FAIL_CNT is incremented when a reg_fail event occurs on any regulator having its
REGFAIL_GO_REC = 1 (that is one counter for all regulators having
REGFAIL_GO_REC = 1)
6
ABIST_BOOST_IGNORED
1: Boost PWM activity has been detected during the ABIST test. So the BOOST comparator
has not been covered by ABIST not to signal a wrong ABIST error
0: Boost ABIST well run
5
LBIST_COMPLETE
Define logical BIST ending
1: LBIST is complete
0: LBIST not complete or not running
4
ABIST_COMPLETE
Define analog BIST ending
1: ABIST is complete
0: ABIST not complete or not running
