c) Serial Transfer Sequence
Notes: 1. Transfer to the common driver must take place immediately after setting up the instruction.
When transfer to the common driver is executed, the transfer is executed by using one of the following
common driver (HD66764) instructions, corresponding to the value set by the IDX2 to 0.

2. The serial transfer period takes a maximum of 1/fosc
3. Serial transfer cannot be executed in standby mode. If the chip enters standby mode during
