All tested BIO input pins match the test pattern in
cbit
[7:0], no BIO input
pins are tested, or all BIO pins are configured as outputs.
Some tested BIO inputs pins do not match the test pattern in
cbit
[7:0],
i.e., no tested BIO pins match the pattern or some (but not all) tested
BIO pins match the pattern.
No tested BIO input pins match the test pattern in
cbit
[7:0], no BIO
input pins are tested, or all BIO pins are configured as outputs.
Some or all tested BIO input pins match the test pattern in

The AWAIT bit is the only bit in
alf
that is cleared on reset.
LOCK is cleared whenever the
pllc
register is written.
§ The MBUSY1 and MBUSY0 flags are read only (writes to these flags are ignored).
