Texas Instruments TM4C1294NCPDT User Manual

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 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 535. 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.

compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
