S12 Clock, Reset and Power Management Unit (S12CPMU)
The internal reset of the MCU remains asserted while the reset generator completes the 768 PLLCLK
cycles long reset sequence. In case the RESET pin is externally driven low for more than these 768
PLLCLK cycles (External Reset), the internal reset remains asserted longer.
