EZ-BLE PRoC Module supports the following five power modes as illustrated in
Figure 4
:
Active mode: This is the primary mode of operation. In this mode, all peripherals are available.
Sleep mode: In this mode, the CPU is in sleep mode, SRAM is in retention, and all the peripherals are available. Any
interrupt wakes up the CPU and returns the system to Active mode.
Deep-Sleep mode: In this mode, the high-frequency clock (IMO) and all high-speed peripherals are off. The WDT, LCD,
I2C/SPI, link layer, and low-frequency clock (32-kHz ILO) are available. Interrupts from GPIO, WDT, or SCBs can cause a
wakeup. The current consumption in this mode is 1.3 µA for all PRoC BLE devices in the family.
Hibernate mode: This power mode provides a best-in-class current consumption of 150 nA while retaining SRAM,
programmable logic, and the ability to wake up from an interrupt generated by a GPIO.
Stop mode: This power mode retains the GPIO states. Wakeup is possible by using the external reset (XRES) pin on the
module. The current consumption in this mode is only 60 nA.

SDWCLK and SWDIO connections can be multiplexed as the functional options listed in each of the respective rows and can be
used for programming without the need to reconfigure the device I/O.
