Serial clock counter
This counter counts the serial clocks that are output and the serial clocks that are input during transmit/receive
operations and is used to verify that 8-bit data was transmitted or received.
Interrupt request signal generator
This circuit controls the generation of interrupt request signal (INTIIC0).
An I
• Eighth or ninth clock of the serial clock (set by WTIM bit
• Interrupt request generated when a stop condition is detected (set by SPIE bit
In master mode, this circuit generates the clock output via the SCL pin from a sampling clock.
This circuit controls the wait timing.
These circuits are used to output and detect various control signals.
This circuit generates the hold time for data corresponding to the falling edge of the serial clock.
Note WTIM bit: Bit 3 of IIC control register 0 (IICC0)
2
C interrupt is generated following either of two triggers.
SPIE bit: Bit 4 of IIC control register 0 (IICC0)
