NOTES: A. Upon power up, SYSCLKOUT is XCLKIN/2 if the PLL is enabled. Since both the XTIMCLK and CLKMODE bits in the XINTCNF2
register come up with a reset state of 1, SYSCLKOUT is further divided by 4 before it appears at XCLKOUT. This explains why
XCLKOUT = XCLKIN/8 during this phase.
B. The state of the GPIO pins is undefined (i.e., they could be input or output) until the 1.8-V (or 1.9-V) supply reaches at least 1 V
and 3.3-V supply reaches 2.5 V..
