Figure 12 COM Driver Interface Control Instruction
IDX2-0: Index bits that select instructions for the common driver. The instruction that corresponds to the
n _{setting made here is transferred, with the index, to the common driver via the serial interface. These}
tio ^{instructions are transferred in bit rows as shown below. The upper 3 bits correspond to IDX2-0. The}
IDX2-0 setting at the time of transfer selects the instruction for the common driver as listed below.
ifica ^{To change an instruction setting on the common driver, first change the instruction bit on the HD66765,}
select the instruction, which includes the changed instruction bit, from the list below, by setting IDX2-0
as required. The instruction is transferred to the common driver as the transfer starts (TE=1), and is the
c _executed.
pe _{TE: Serial transfer enable for the common driver. When TE=0, serial transfer is possible. Do not change}
S _{the instruction during transfer. When TE=1, transfer starts. TE returning to 0 indicates the end of the}
y ^{transfer. Note that, serial transfer to the common driver requires 18 clock cycles at most. Do not change}
r _{the instruction during the transfer.}
ina ^{* New instructions should be transferred to the common driver soon after they have been set on the}
