Condition for clearing (EXC0 = 0)
• When a start condition is detected

• Cleared by LREL0 = 1 (exit from communications)
• When the IICE0 bit changes from 1 to 0 (operation
• Reset
Condition for clearing (COI0 = 0)
• When a start condition is detected
• When a stop condition is detected
• Cleared by LREL0 = 1 (exit from communications)
• When the IICE0 bit changes from 1 to 0 (operation
• Reset

(WREL0) of the IICA control register 0 (IICACTL0) is set to 1 during the ninth clock and wait is
canceled, after which the TRC0 bit is cleared (reception status) and the SDAA0 line is set to high
impedance. Release the wait performed while TRC0 bit is 1 (transmission status) by writing to the
IICA shift register.

Transmit status. The value in the SO0 latch is enabled for output to the SDAA0 line (valid starting at
the falling edge of the first byte’s ninth clock).
