Programmable bus monitor or timer
General purpose I/O pins
Operating frequency
16 programmable GPIO interface pins
4 pins programmable with level-sensitive
interrupt
36, 46, or 55 MHz internal clock operation from
18.432 MHz crystal
fMAX = 36, 46, or 55 (grade–dependent)
System clock source by external quartz crystal
or crystal oscillator, or clock signal
