Register Map
Table 7-1 on page 145 lists the Hibernation registers. All addresses given are relative to the Hibernation
Module base address at 0x400F.C000.
Note:
When the hibernation module has no externally applied voltage and detects a change to either
VDD or VBAT, it resets all hibernation module registers to the value in Table 7-1 on page 145.
Reset During Hibernation Module Disable
When the module has either not been enabled or has been disabled by software, the reset is
passed through to the Hibernation module circuitry and the internal state of the module is reset.
Reset While HIB Module is in Hibernation Mode
While in Hibernation mode, or while transitioning from Hibernation mode to run mode (leaving
the power cut), the reset generated by the POR circuitry of the device is suppressed, and the
state of the Hibernation module's registers is unaffected.
Reset While HIB Module is in Normal Mode
While in normal mode (not hibernating), any reset is suppressed, and the content/state of the
control and data registers is unaffected.
Software must initialize any control or data registers in this condition. Therefore, software is the
only mechanism to enable or disable the oscillator and real-time clock operation, or to clear
contents of the data memory. The only state that must be cleared by a reset operation while not
in Hibernation mode is any state that prevents software from managing the interface.
HIBRTCC, HIBRTCM0, HIBRTCM1, HIBRTCLD, HIBRTCT, and HIBDATA are on the
Hibernation module clock domain and require a delay of t
accesses. See “Register Access Timing” on page 138.
