interface. See Tables 13, 14, 16 and 17 for CAS bit
positions in CSTo1 and CSTi2.
Reset Operation (Initialization)
The MT9079 can be reset using the hardware
RESET pin (see pin description for external reset
circuit requirements) or the software reset bit RST
(page 1, address 11H). During the reset state, TxA
and TxB are low. When the device emerges from its
reset state it will begin to function with the default
settings described in Table 3.
