To minimize current in HALT mode, all GPIO pins which are configured as inputs must be
driven to one of the supply rails (V
On-chip peripherals in ZNEO Z16F Series parts automatically enter a low power mode
after Reset and whenever the peripheral is disabled. To minimize power consumption,
unused peripherals must be disabled. See the individual peripheral chapters for specific
register settings to enable or disable the peripheral.
User programmable option bits are available in some versions of the ZNEO Z16F Series
devices that enable very low power STOP mode operation. These options include disabling
the VBO protection circuits and disabling the WDT oscillator. For detailed description of
the user options that affect power management, see
