(5) IICA control register 1 (IICCTL1)
Address: F0231H
IICCTL1
Symbol
This register is used to set the operation mode of I
IICCTL1 can be set by a 1-bit or 8-bit memory manipulation instruction. However, the CLD and DAD bits are
read-only.
Set the IICCTL1 register, except the WUP bit, while operation of I
register 0 (IICCTL0) is 0).
Reset signal generation clears this register to 00H.
Notes 1.
To shift to STOP mode when WUP = 1, execute the STOP instruction at least three clocks after setting (1) WUP
(see Figure 14-22 Flow When Setting WUP = 1).
Clear (0) WUP after the address has matched or an extension code has been received. The subsequent
communication can be entered by clearing (0) WUP. (The wait must be released and transmit data must be
written after WUP has been cleared (0).)
The interrupt timing when the address has matched or when an extension code has been received, while WUP
= 1, is identical to the interrupt timing when WUP = 0. (A delay of the difference of sampling by the clock will
occur.) Furthermore, when WUP = 1, a stop condition interrupt is not generated even if the SPIE bit is set to 1.
Condition for clearing (WUP = 0)
• Cleared by instruction (after address match or
extension code reception)

Bits 4 and 5 are read-only.
The status of IIC status register (IICS) must be checked and WUP must be set during the
