VSPI pin undervoltage monitor
The device implements a monitor of VSPI pin voltage in order to detect SPI interface supply below expected
value; this is required to avoid unexpected device wakeup from standby state caused by CSN pin driven low by
VSPI drop or shutoff (uC in standby condition).
When VSPI voltage is lower than VSPI_UV threshold (refer to Table 4), device wake up from standby state
through CSN pin is inhibited.
