Serial interface IIC0 consists of the following hardware units.
(1) Peripheral enable register 0 (PER0)
(2) IIC shift register 0 (IIC0)
(3) Slave address register 0 (SVA0)
(4) IIC control register 0 (IICC0)
(5) IIC status register 0 (IICS0)
(6) IIC flag register 0 (IICF0)
(7) IIC clock select register 0 (IICCL0)
(8) IIC function expansion register 0 (IICX0)
(9) Port mode register 6 (PM6)
Bit 4 of this register is used to enable or stop operation of serial interface IIC0. The default value of this bit is
set to stop the operation of serial interface IIC0.
IIC0 is a register that converts 8-bit serial data into 8-bit parallel data or vice versa in synchronization with the
serial clock. This register is used for both transmission and reception.
This register stores the source address when the microcontroller is used as a slave.
This register is used to enable or stop the operation of I
This register indicates the status of I
This register is used to set an operation mode of I
This register is used to set the transfer clock of I
This register is used to set the function expansion of I
This register is used to set port 6 in the input or output mode in 1-bit units.
