MC68HC912B32 microcontroller  is a 16-bit device composed of
standard on-chip peripherals including a 16-bit central processing
unit (CPU12), 32-Kbyte flash EEPROM, 1-Kbyte RAM, 768-byte EEPROM, an
asynchronous serial communications interface (SCI), a serial
peripheral interface (SPI), an 8-channel timer and 16-bit pulse
accumulator, an 8-bit analog-to-digital converter (ADC), a
four-channel pulse-width modulator (PWM), and a J1850-compatible byte
data link communications module (BDLC). The chip is the first 16-bit
microcontroller to include both byte-erasable EEPROM and flash EEPROM
on the same device. System resource mapping, clock generation,
interrupt control and bus interfacing are managed by the Lite
integration module (LIM). The MC68HC912B32 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.


Для программирования FLASH подключить 
69 вывод Vfp MCU к источнику +12V, 50mA.

12V можно получить с контакта 
VPP6 (+15V) левого дополнительного разьема 
с помощью резистора 100 Ом последовательно и 
стабилитрона на 12V между Vfp и GND.
Установить джампера VPRG и 711.

В режиме чтения напряжение на этом выводе 
должно быть равно напряжению питания.
