17.3 Registers to Control Serial Interface IIC0
Serial interface IIC0 is controlled by the following seven registers.
(1) IIC control register 0 (IICC0)
• IIC control register 0 (IICC0)
• IIC flag register 0 (IICF0)
• IIC status register 0 (IICS0)
• IIC clock selection register 0 (IICCL0)
• IIC function expansion register 0 (IICX0)
• Port mode register 6 (PM6)
• Port register 6 (P6)
This register is used to enable/stop I
IICC0 is set by a 1-bit or 8-bit memory manipulation instruction. However, set the SPIE0, WTIM0, and ACKE0
bits while IICE0 bit = 0 or during the wait period. These bits can be set at the same time when the IICE0 bit is
set from “0” to “1”.
Reset signal generation sets IICC0 to 00H.
