AP0101CS HDR: Image Signal Processor (ISP)

System Interfaces

Note:

If the system cannot support this power supply slew rate, then power supplies must be designed

to overcome inrush currents in Table 24, “Inrush Current,” on page 38.

Reset

The AP0101CS has 3 types of reset available:

• A hard reset is issued by toggling the RESET_BAR signal

• A soft reset is issued by writing commands through the two-wire serial interface

• An internal power-on reset

Table 7 shows the output states when the part is in various states.
