Either all the tested BIO input pins match the test pattern, none of the BIO input
pins are tested, or all the BIO pins are configured as outputs.
SOME false—some or all tested BIO inputs pins do not match the test pattern.
Either none of the tested BIO input pins match the test pattern, none of the BIO
input pins were tested, or all the BIO pins are configured as outputs.
SOME true—some or all tested BIO input pins match the test pattern.
Some or all of the tested BIO input pins match the test pattern.
ALL false—either no tested BIO input bits match the test pattern, none of the
BIO input pins are tested, or all the BIO pins are configured as outputs.
Not all (some or none) of the tested BIO input bits match the test pattern.
ALL true—either all tested BIO input bits match the test pattern, none of the BIO
input pins inputs are tested, or all the BIO pins are configured as outputs.
LOCK is cleared on device reset or if the
pllcon
register is written.
For this column, X indicates unknown on powerup reset and unaffected on subsequent reset.
