Clocks and Power Control
The values of the PITRTCLK clock division and TMBCLK clock division can be changed by software.
The RTDIV bit value in the SCCR register defines the division of PITRTCLK. All possible combinations
of the TMBCLK divisions are listed in
8.5.1
The general system clocks (GCLK1C, GCLK2C, GCLK1, GCLK2, GCLK1_50, and GCLK2_50) are the
basic clock supplied to all modules and sub-modules on the MPC561/MPC563. GCLK1C and GCLK2C
are supplied to the RCPU and to the BBC. GCLK1C and GCLK2C are stopped when the chip enters the
doze-low power mode. GCLK1 and GCLK2 are supplied to the SIU and the clock module. The external
bus clock GCLK2_50 is the same as CLKOUT. The general system clock defaults to VCO/2 = 20 MHz
(assuming a 20-MHz system frequency) with default power-on reset MF values.

To ensure correct operation of the time base, keep the system clock to time
base clock ratio above 4 and always set SCCR[TBS] = 1 when running on
the backup clock (limp mode).
