Software Reset
The MAX7456 features a Software Reset bit (VM0[1])
that, when set high, clears the display memory and
resets all registers to their default values except the
OSD Black Level register (OSDBL). After 100s (typi-
cal), STAT[6] can be polled to verify that the reset
process is complete.
Hardware Reset
The MAX7456 provides a hardware reset input (RESET)
that functions the same as the POR. All registers are
reset to their default values and are not accessible for
reading/writing when RESET is driven low. The resetting
process requires a
≥ 50ms wide RESET pulse, and no
other activities are allowed during this interval. All SPI
registers are reset to their default values 100s after the
rising edge of RESET. The display memory is reset to
its default value of 00H in all locations 20s after the ris-
ing edge of RESET. RESET takes precedence over the
Software Reset bit. After RESET has been deasserted,
STAT[6] can be polled to verify that the reset sequence
is complete.
