Note:
²*² The operating current IDD1 listed here is the additional current consumed when the slave SPI interface in the
UART module is enabled and the UART interface is disabled. Similarly, the operating current IDD2 here is the
additional current consumed when both the slave SPI interface and UART interface are enabled. If the UART
module is enabled, either IDD1 or IDD2 should be added to calculate the relevant operating current of the device
for different conditions. To calculate the standby current for the whole device, the standby current shown above
should be taken into account.
