C includes the following hardware.
The IIC register is used to convert 8-bit serial data to 8-bit parallel data and to convert 8-bit parallel data to 8-
bit serial data. The IIC register can be used for both transmission and reception.
Write and read operations to the IIC register are used to control the actual transmit and receive operations.
The IIC register can be read or written in 8-bit units.
This register is cleared to 00H after reset.
The SVA register sets local addresses when in slave mode.
The SVA register can be read or written in 8-bit units.
This register is cleared to 00H after reset.
The SO latch is used to retain the SDA pin’s output level.
This circuit generates an interrupt request when the address received by this register matches the address
value set to slave address register (SVA) or when an extension code is received.
This selects the sampling clock to be used.
