2. Value when the processor clock control register (PCC) is set to 0011 and the PD75238 is operated
3. Value when the PCC is set to 0000 and the PD75238 is operated in the low-speed mode
4. This value applies also when the subsystem clock oscillates.
5. This value applies when the system clock control resistor (SCC) is set to 1001 to stop the main
