REGISTER WRITE OPERATION
All Write operations for the serial control port use 16-bit
data words. Figure 6 shows the control data word format.
The most significant bit is the Read/Write (R/W) bit. When
set to ‘0’, this bit indicates a Write operation. There are
seven bits, labeled IDX[6:0], that set the register index (or
address) for the Write operation. The least significant eight
bits, D[7:0], contain the data to be written to the register
specified by IDX[6:0].
Figure 7 shows the functional timing diagram for writing the
serial control port. ML is held at a logic ‘1’ state until a
register needs to be written. To start the register write cycle,
ML is set to logic ‘0’. Sixteen clocks are then provided on
MC, corresponding to the 16-bits of the control data word on
MDI. After the sixteenth clock cycle has completed, ML is
set to logic ‘1’ to latch the data into the indexed mode
control register.

SINGLE REGISTER READ OPERATION
Read operations utilize the 16-bit control word format shown
in Figure 6. For Read operations, the Read/Write (R/W) bit
is set to ‘1’. Read operations ignore the index bits, IDX[6:0],
of the control data word. Instead, the REG[6:0] bits in
Control Register 11 are used to set the index of the register
that is to be read during the Read operation. Bits IDX[6:0]
should be set to 00
H
for Read operations.
Figure 8 details the Read operation. First, Control Register
11 must be written with the index of the register to be read
back. Additionally, the INC bit must be set to logic ‘0’ in
order to disable the Auto-Increment Read function. The
Read cycle is then initiated by setting ML to logic ‘0’ and
setting the R/W bit of the control data word to logic ‘1’,
indicating a Read operation. MDO remains at a high-imped-
ance state until the last 8 bits of the 16-bit read cycle, which
