4.2.2 General purpose registers 0 to 3
4.2.3 General purpose register 4
Table 43.
The general purpose registers retain data through the Deep power-down mode when
power is still applied to the V
Only a “cold” boot when all power has been completely removed from the chip will reset
the general purpose registers.
Table 44.
The general purpose register 4 retains data through the Deep power-down mode when
power is still applied to the V
Only a “cold” boot, when all power has been completely removed from the chip, will reset
the general purpose registers.
Remark: If there is a possibility that the external voltage applied on pin V
2.2 V during Deep power-down, the hysteresis of the WAKEUP input pin has to be
disabled in this register before entering Deep power-down mode in order for the chip to
wake up.
