11.2 Power-On Reset
The CSP1027 has a power-on reset circuit that automatically clears the device upon power-on. If the supply voltage
falls below V

, the device must be reset. Figure 40 on page 57 shows two separate events: an initial power-
on and a power-on following a drop in the power supply.
* See Table 11 on page 47.

Note: The device needs to be clocked for at least six CLK cycles during reset after power-on. Otherwise, high and unstable current may flow.
