NOTES:
1. The nominal slow reference frequency is 32.768 kHz, but can range from
20 to 50 kHz. The nominal fast reference frequency is 4.194 MHz, but can
range from 1MHz to 6.25 MHz.
System hardware and software allow changes in clock rate during operation. Because
the MCUs are a fully static design, register and memory contents are not affected by
clock rate changes.
High-density complementary metal-oxide semiconductor (HCMOS) architecture
makes the basic power consumption low. Power consumption can be minimized by
stopping the system clocks. The M68HC16 instruction set includes a low-power stop
(LPSTOP) command that efficiently implements this capability. Individual stop bits in
each module allow for selective power reduction.
Documentation for the Modular Microcontroller Family follows the modular construc-
tion of the devices in the product line. Each device has a comprehensive user’s man-
ual that provides sufficient information for normal operation of the device. The user’s
manual is supplemented by module reference manuals that provide detailed informa-
tion about module operation and applications. Refer to Freescale publicationAdvanced
Microcontroller Unit (AMCU) Literature (BR1116/D) for a complete list of documenta-
tion to supplement this manual.
