Register 21: HIB Tamper Control (HIBTPCTL), offset 0x400
The Tamper Control (HIBTPCTL) register provides control of the module.
Note:
Except for the HIBIO and a portion of the HIBIC register, all other Hibernation module
registers are on the Hibernation module clock domain and have special timing requirements.
Software should make use of the
registers are on the Hibernation module clock domain and have special timing requirements.
Software should make use of the
WRC
bit in the HIBCTL register to ensure that the required
timing gap has elapsed. If the
WRC
bit is clear, any attempted write access is ignored. See
“Register Access Timing” on page 565. The HIBIO register and bits
RSTWK
,
PADIOWK
and
WC
of the HIBIC register do not require waiting for write to complete. Because these registers
are clocked by the system clock, writes to these registers/bits are immediate.
Writing to registers other than the HIBCTL and HIBIM before the
CLK32EN
bit in the HIBCTL
register has been set may produce unexpected results.
Note:
Errant writes to the Tamper registers are protected by the Hibernate HIBLOCK register.
