• Manufacturer Part Number: mc68hc11k4
• Description: Mc68hc11k1 Microcontroller
• Manufacturer: Freescale Semiconductor, Inc

M68HC11K Family
MOTOROLA
NOTE:
Ports B, F, G, and H contain on-chip pullup devices which are enabled
by the port pullup assignment register (PPAR) described in
Pullup
At reset, the ports are configured as high-impedance GPIO inputs
(except for ports B, C, F, and port G pin 7 in expanded modes). The
contents of the data latches is undefined. If any of the bidirectional pins
are changed to outputs before writing to the associated data registers,
the undefined contents will be driven on the pins. This is indicated by the
letter U in the register descriptions that follow.
Throughout this manual, the registers are discussed by function. In the
event that not all bits in a register are referenced, the bits that are not
discussed are shaded.
