Note Bit 0 is fixed to 0.
The SO latch is used to retain the SDAA0 pin’s output level.
This circuit generates an interrupt request (INTIICA0) when the address received by this register matches the
address value set to the slave address register 0 (SVA0) or when an extension code is received.
This counter counts the serial clocks that are output or input during transmit/receive operations and is used to verify
that 8-bit data was transmitted or received.
This circuit controls the generation of interrupt request signals (INTIICA0).
An I
• Falling edge of eighth or ninth clock of the serial clock (set by WTIM0 bit)
• Interrupt request generated when a stop condition is detected (set by SPIE0 bit)
Remark
In master mode, this circuit generates the clock output via the SCLA0 pin from a sampling clock.
This circuit controls the wait timing.
These circuits generate and detect each status.
This circuit generates the hold time for data corresponding to the falling edge of the serial clock.
This circuit generates a start condition when the STT0 bit is set to 1.
However, in the communication reservation disabled status (IICRSV bit = 1), when the bus is not released (IICBSY
bit = 1), start condition requests are ignored and the STCF bit is set to 1.
This circuit generates a stop condition when the SPT0 bit is set to 1.
2
C interrupt request is generated by the following two triggers.
Address: FFA6H
WTIM0 bit: Bit 3 of IICA control register 0 (IICACTL0)
SPIE0 bit: Bit 4 of IICA control register 0 (IICACTL0)
