Description
Set this bit to drive the CRST3/CC82 pin High with the on-chip pull-up (according to IODIS2 bit
value). The pin can then be an input (read in STATUSB register).
Clear this bit to drive a low level on the CC82 pin (according to IODIS2 bit value).
Set this bit to drive the CIO5 pin High with the on-chip pull-up when isolated from the host (See
“ITDIS ()” on page 59.). The pin can then be an input (read in STATUSB register).
Clear this bit to drive a low level on the CIO5 pin when isolated from the host.
Set this bit to drive the CIO4 pin High with the on-chip pull-up when isolated from the host (See
“ITDIS ()” on page 59.). The pin can then be an input (read in STATUSB register).
Clear this bit to drive a low level on the CIO4/C45 pin when isolated from the host.
Set this bit to drive the CIO3/CC42 pin High with the on-chip pull-up when isolated from the host
(See “ITDIS ()” on page 59.). The pin can then be an input (read in STATUSB register).
Clear this bit to drive a low level on the CIO3/CC42 pin when isolated from the host.
This bit is CIO3 when AUX=0 or when AUX=1 and IFN=2, otherwise it is CC42.
Set this bit to drive the CIO2 pin High with the on-chip pull-up when isolated from the host (See
“ITDIS ()” on page 59.). The pin can then be an input (read in STATUSB register).
Clear this bit to drive a low level on the CIO2 pin when isolated from the host.
