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 100μs (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 100μs after the
rising edge of
RESET
. The display memory is reset to
its default value of 00H in all locations 20μs 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.
