2.6 Write Mode Register Instruction
(WRMR)
The Write Mode Register instruction (WRMR) allows the
user to write to the bits in the MODE register as shown
in Table 2-2. This allows for setting of the Device
operating mode. Several of the bits in the MODE
register must be cleared to ‘0’. See Figure 2-8 for the
WRMR timing sequence.
