(g) Interrupt request signal generation circuit
Controls the generation of interrupt request signals.
SMB interrupts are generated with the following two triggers.
8th clock or 9th clock of serial clock (set with WTIM0 bit
Generation of interrupt request at detection of stop condition (set with bit SPIE0
Note
)
Note
)
Note
WTIM0 bit: SMB control register 0 (SMBC0) bit 3
SPIE0 bit:
SMB control register 0 (SMBC0) bit 4
(h) Serial clock control circuit
In master mode, generates the clock to be output to the SCL0 pin from the sampling clock.
(i)
Serial clock wait control circuit
Controls the wait timing.
(j)
Acknowledge output circuit, stop condition detection circuit, start condition detection circuit,
acknowledge detection circuit
Perform output and detection of control signals.
(k) Data hold time correction circuit
Generates the data hold time from the falling edge of the serial clock.
