MAX7456 Register Description
Access to all MAX7456 operations, including display-
memory and character-memory access, are through
the SPI registers listed in Table 3. There is no direct
access to the display and character memories through
the SPI port. See the
Applications Information
section
for step-by-step descriptions of the SPI operations
needed to access the memories.
The register format used in this data sheet is
REGISTER_NAME [BIT_NUMBERS]. For example, bit 1 in
Video Mode 0 register is written as VM0[1].
