Resets
Power-On Reset
The MAX7456’s power-on reset circuitry (POR) pro-
vides an internal reset signal that is active after the sup-
ply voltage has stabilized. The internal reset signal
resets all registers to their default values and clears the
display memory. The register reset process requires
100s, and to avoid unexpected results, read/write
activity is not allowed during this interval. The display
memory is reset, and the OSD is enabled typically
50ms after the supply voltage has stabilized and a sta-
ble 27MHz clock is available. The user should avoid
SPI operations during this time to avoid unexpected
results. After 50ms (typical), STAT[6] can be polled to
verify that the reset sequence is complete (Figure 22).
