Introduction
The MC68HC912BD32 microcontroller unit (MCU) is a16-bit device
composed of standard on-chip peripherals including a 16-bit central
processing unit (CPU12), 32K byte flash EEPROM, 1K byte RAM,
768 byte EEPROM, an asynchronous serial communications interface
(SCI), a serial peripheral interface (SPI), an 8-channel timer and 16-bit
pulse accumulator, a 10-bit analog-to-digital converter (ADC), a
four-channel pulse-width modulator (PWM), and a Byteflight™ module.
System resource mapping, clock generation, interrupt control and bus
interfacing are managed by the Lite integration module (LIM). The
MC68HC912BD32 has full 16-bit data paths throughout, however, the
multiplexed external bus can operate in an 8-bit narrow mode so single
8-bit wide memory can be interfaced for lower cost systems.
