The SO latch is used to retain the SDA0 pin’s output level.
This circuit generates an interrupt request (INTIICA) when the address received by this register matches the
address value set to the slave address register (SVA) 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 (INTIICA).
An I
• Falling edge of 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)
Remark
In master mode, this circuit generates the clock output via the SCL0 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 STT 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 SPT bit is set to 1.
2
C interrupt request is generated by the following two triggers.
WTIM bit:
SPIE bit:
Bit 3 of IICA control register 0 (IICCTL0)
Bit 4 of IICA control register 0 (IICCTL0)
