General Description
1.1 Introduction
The MC68HC912B32, MC68HC12BE32 and MC68HC(9)12BC32, are 16-bit microcontroller units
(MCUs) composed of standard on-chip peripherals. The multiplexed external bus can also operate in an
8-bit narrow mode for interfacing with single 8-bit wide memory in lower-cost systems. There is a slight
feature set difference between the four pin-for-pin compatible devices as shown in
