Chapter 7 Internal Clock Generator (ICG) Module
The MC9S08GB/GT microcontroller provides one internal clock generation (ICG) module to create the
system bus frequency. All functions described in this section are available on the MC9S08GB/GT
microcontroller. The EXTAL and XTAL pins share port G bits 2 and 1, respectively. Analog supply lines

* ICGLCLK is the alternate BDC clock source for the MC9S08GB/GT.
Freescale Semiconductor recommends that FLASH location $FFBE be
reserved to store a nonvolatile version of ICGTRM. This will allow
debugger and programmer vendors to perform a manual trim operation and
store the resultant ICGTRM value for users to access at a later time.
