18.2 Configuration of Serial Interface IIC0
(1) IIC shift register 0 (IIC0)
(2) Slave address register 0 (SVA0)
Serial interface IIC0 includes the following hardware.
Address: FF1FH After reset: 00H
Symbol
IIC0
Caution
Address: FFABH After reset: 00H
Symbol
SVA0
Note Bit 0 is fixed to 0.
IIC0 is used to convert 8-bit serial data to 8-bit parallel data and vice versa in synchronization with the serial clock.
IIC0 can be used for both transmission and reception.
Write and read operations to IIC0 are used to control the actual transmit and receive operations.
IIC0 is set by an 8-bit memory manipulation instruction.
RESET input clears IIC0 to 00H.
This register sets local addresses when in slave mode.
SVA0 is set by an 8-bit memory manipulation instruction.
RESET input clears SVA0 to 00H.
CHAPTER 18 SERIAL INTERFACE IIC0 ( PD780024AY, 780034AY SUBSERIES ONLY)
Do not write data to IIC0 during data transfer.
