Note that the two ports are independent so that, for example, PORT1 can operate with 8 bit enable strobes and PORT2
can operate with 16 bit enable strobes.

CS
Delays due to internal processor timing which are transparent to the MT9122.
The MT9122:
outputs transmit data on the falling edge of SCLK
The falling edge of CS indicates that a COMMAND/ADDRESS byte will be transmitted from the microprocessor. The subsequent
byte is always data followed by CS returning high.
A new COMMAND/ADDRESS byte may be loaded only by CS cycling high then low again.
The COMMAND/ADDRESS byte contains:
1 bit - Read/Write
6 bits - Addressing Data
1 bit - Unused
