PARALLEL I/O
TECHNICAL DATA
6-1
SECTION 6
PARALLEL I/O
The MC68HC11D3 has four 8-bit I/O ports; A, B, C, and D. In single-chip and bootstrap
modes, all ports are parallel I/O data ports. In expanded multiplexed and test modes,
ports B and C, and lines DATA6/AS and DATA7/R/W are a memory expansion bus
with port B as the high order address bus, port C as the multiplexed address and data
bus, AS as the demultiplexing signal, and R/W as the data bus direction control. Refer
to Table 6-1, which is a summary of the ports and their shared functions:
6.1 Port A
Port A bits handle the timer functions and can also be used as general-purpose I/O. In
both the normal operating modes, port A can be configured for four timer input capture
(IC) and three timer output compare (OC) functions, or four OC and three IC functions
with either a pulse accumulator input (PAI) or a fifth OC function.
*This pin is not bonded in the 40-pin version.
6.2 Port B
In single-chip mode, all port B pins are general-purpose I/O (PB[7:0]). In expanded
multiplexed mode, all port B pins act as high-order address bits (ADDR[15:8]).
