Abstract: testing of pll 68HCO8
Contextual Info: CGM08 A Powerful, Flexible Clock Signal Generator The Clock Generation Module CGM08 generates two important clock signals for 68HC08 devices: a crystal clock signal (CGMXCLK) for the COP watchdog module and SCI baud rate generator, and a divide-by-two base

Contextual Info: TBM08 The 68HC08's Time Base Module TBM08 generates a periodic real-time interrupt. The frequency of the periodic interrupt is determined by the value of the programmable time base register and the oscillator. Periodic interrupts of 1 Hz, 4 Hz, 16 Hz, and 256 Hz can be generated when using a 32.768 kHz crystal.

TIM08

Abstract: 68HC05
Contextual Info: TIM08 Expanded Functionality The 68HC08's Timer Interface Module TIM08 offers flexible configurations to service a variety of timing applications. Readers familiar with the 68HC05 16-bit timer modules will discover that the TIM08 provides all the same features (input capture, output compare, interrupt on overflow) with additional functions, including:

Abstract: SCI08 power line Communication microcontroller 68HC05 HC05
Contextual Info: SCI08 The 68HC08's Asynchronous Serial Communications Interface module SCI08 has all the capabilites of the 68HC05's SCI as well as additional enhancements. It is an independent serial I/O subsystem (full-duplex UARTtype asynchronous system). The SCI can be used for communications between the microcontroller and a

Contextual Info: Keyboard Interrupt Typical microcontroller applications have some sort of user input in the form of pressing a button or keypad. In battery powered applications it is desirable to have the MCU in a low power wait or stop mode while waiting for key pad input. When a user presses a key on the keypad an interrupt is generated. The interrupt wakes the MCU
