Section 18 Power-Down Mode
4. Hi-Z state, except for the RTC module interface pins
5. Undefined, except for DDR-SDRAM interface pins
6. AR: auto-refresh: SR: self-refresh
7. S1 and S0 are the output states on the STATUS1 and STATUS0 pins, respectively.
8. Although the clock supply to the internal circuitry is stopped, the clock output on the
CLKOUT pin continues if the CKONE bit in PLLCR of the CPG is set to 1.
