Note: 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., page 21.
2. If the device is in battery back-up; NOT on VCC (see RAM Clear External (CLR1EXT and CLR2EXT), page 18).
3. If TIEX = '1.'
4. If ABE = '1.'
