On the MC68HC11F1, 54 pins are arranged into six 8-bit ports (ports A, B, C, E, F, and G) and
one 6-bit port (port D). On the MC68HC11FC0, either 52 or 49 pins are available, depending on
the package. General-purpose I/O port signals are discussed briefly in the following pragraphs.
For additional information, refer to 7 Parallel Input/Output.
Port A is an 8-bit general-purpose I/O port (PA[7:0]) with a data register (PORTA) and a data
direction register (DDRA). Port A pins share functions with the 16-bit timer system. Out of reset,
PA[7:0] are general-purpose high-impedance inputs.
Port B is an 8-bit output-only port. In single-chip modes, port B pins are general-purpose output
pins (PB[7:0]). In expanded modes, port B pins act as the high-order address lines ADDR[15:8].
Port C is an 8-bit general-purpose I/O port with a data register (PORTC) and a data direction
register (DDRC). In single-chip modes, port C pins are general-purpose I/O pins PC[7:0]. In
expanded modes, port C pins are configured as data bus pins DATA[7:0].
Port D is a 6-bit general-purpose I/O port with a data register (PORTD) and a data direction
register (DDRD). The six port D lines PD[5:0] can be used for general-purpose I/O or for the serial
communications interface (SCI) or serial peripheral interface (SPI) subsystems.
Port E is an 8-bit input-only port that is also used as the analog input port for the analog-to-digital
converter. Port E pins that are not used for the A/D system can be used as general-purpose
inputs. However, PORTE should not be read during the sample portion of an A/D conversion
sequence.
Port F is an 8-bit output-only port. In single-chip mode, port F pins are general-purpose output
pins PF[7:0]. In expanded mode, port F pins act as the low-order address outputs ADDR[7:0].
Port G is an 8-bit general-purpose I/O port. When enabled, four chip select signals are alternate
functions of PG[7:4].
The A/D system is not available on the MC68HC11FC0. PE7 and PE0 are not
available on the 80-pin MC68HC11FC0. PE7, PE4, and PE0 are not available on
the 64-pin MC68HC11FC0.
PG[1:0] are not available on the 64-pin MC68HC11FC0.
