00b VCC rise window selection
To rise from 0 to its selected value (see ct_pcr_reg register), the"
time needed by VCC depends on the capacitance. For more
flexibility, it is possible to choose between 4 window time:
• 00: t = 5T (~120 us)
• 01: t = 10T (~240 us)
• 10: t = 16T (~380 us)
• 11: t = 21T (~500 us) - recommended
"See the activation sequence description for T definition.
