6.11 Internal Pullup Resistors
M68HC11K Family
MOTOROLA
NOTE:
NOTE:
Address: $002C
Address: $003F
M68HC11KS series devices contain selectable internal pullup resistors
for ports B, F, G, and H. The resistors for each port are enabled by
setting the corresponding bit in the PPAR register. PPAR itself must be
enabled by setting the PAREN bit in the system configuration register
(CONFIG). Refer to
xPPUE — Port x Pin Pullup Enable Bits
FPPUE and BPPUE do not apply in expanded mode because port F and
B are address outputs.
CONFIG is writable once in normal modes and writable at any time in
special modes.
