(6) Slave address register 0 (SVA0)
(5) IIC shift register 0 (IIC0)
After reset: 00H
IIC0 is used for serial transmission/reception (shift operations) that are synchronized with the serial clock. It can
be read from or written to in 8-bit units, but data should not be written to IIC0 during a data transfer.
SVA0 holds the I
It can be read from or written to in 8-bit units, but bit 0 should be fixed to 0.
