(4) IICA control register 1 (IICACTL1)
Address: FFA8H
IICACTL1
Symbol
This register is used to set the operation mode of I
IICACTL1 can be set by a 1-bit or 8-bit memory manipulation instruction. However, the CLD0 and DAD0 bits
are read-only.
Set IICACTL1, except the WUP bit, while bit 7 (IICE0) of IICA control register 0 (IICACTL0) is 0.
Reset signal generation clears this register to 00H.
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 SPIE0 bit is set to 1.
When WUP = 0 is set by a source other than an interrupt from serial interface IICA, operation as the master
device cannot be performed until the subsequent start condition or stop condition is detected. Do not output a
start condition by setting (1) the STT0 bit, without waiting for the detection of the subsequent start condition or
stop condition.
