Operating modes
Figure 13.
Tamper detect connection options
Note:
These options are connected to those in Table 3.
1.
If the CLRXEXT bit is set, a second tamper to VOUT (TPM2 = '1') during tCLR will not be detected.
2.
If the CLRXEXT bit is set, a second tamper to VOUT (TPM2 = '1') will trigger automatically.
3.
Optional external resistor to VCC allows the user to bypass sampling when power is “on.”
