Tamper current options
Figure 19.
Tamper output timing (with CLR1EXT or CLR2EXT = '1') - available in SOX28 (MX)
package only
1.
If connected to a negative charge pump device, this pin must be isolated from the charge pump by using both n-channel
and p-channel MOSFETs as illustrated in Figure 20 on page 25.
2.
If the device is in battery back-up; NOT on VCC (see Section 2.6.9: RAM clear external (CLR1EXT and CLR2EXT) - available
in SOX28 package only on page 22). VOUT is forced to GND during a tamper event when on VCC.
3.
If TIEX = '1.'
4.
If ABE = '1' and device is in battery backup mode.
