Chapter 1 Device Overview MC9S12XD-Family
1.3
The clock and reset generator module (CRG) provides the internal clock signals for the core and all
peripheral modules.
See 79Chapterf or details on clock generation.
The MCU’s system clock can be supplied in several ways enabling a range of system operating frequencies
to be supported:
The clock generated by the PLL or oscillator provides the main system clock frequencies core clock and
bus clock. As shown in
memories, and the peripherals.
The program Flash memory and the EEPROM are supplied by the bus clock and the oscillator clock.The
oscillator clock is used as a time base to derive the program and erase times for the NVM’s. See the Flash
and EEPROM section for more details on the operation of the NVM’s.
