RTC-Well Input Strap Requirements

All RTC-well inputs must be either pulled up to VCCRTC3P3 or pulled down to ground
while in the G3 state. RTCRST_B, when configured as shown in
requirement. This will prevent these nodes from floating in G3, and correspondingly will
prevent I
RTC_EXT_CLK_EN_B input signal should also be configured with an external 10k pull-
down, which selects the external RTC clock source, if operating from a battery in G3.
