IPWR_13		MCU IDD in IDLE mode w/BUCK mode selected	PLL 128 MHz	57.5	—	µA/MHz	VDD = AVDD = 3.3V
IPWR_15			PLL 128 MHz	72.42	—	µA/MHz	VDD = AVDD = 2.4V
IPWR_21			FRC 8 MHz	2.47	—	mA	VDD = AVDD = 3.3V
IPWR_23			FRC 8 MHz	2.61	—	mA	VDD = AVDD = 2.4V
Note: Conditions: All Peripherals disabled with PMD bits, except EIC for external interrupt. Disable the JTAG Port. RF System OFF. CMCC Disable. PreFetch Cache Disable. All GPIOs are set as input and pulled up. PB1, PB2, PB4 and PB5 clocks are divided by 2, while the PB3 clock is divided by 20. PMU 1 MHz clock from FRC div by 8. LPRC set as LPCLK. SOSC is disabled. RTCC is enabled as wake-up source. WCM memories configured in Retention + NAP mode. DSU is disconnected. Entry to Sleep mode disabled and the WFI instruction executed: On exit by RTCC timeout, verify the RCON status to ensure the system is in IDLE mode.
