PURPOSE: To obtain the serial communication method and the serial communication circuit in which increase in the circuit scale is suppressed and data quantity to be received is increased. CONSTITUTION: A communication serial signal reception section 33 compares a transfer destination address of serial data with an address set to its own address setting section 34 and provides an output of serial data in succession to the transfer destination address converted into parallel data to data latch sections 35-1, 35-2, ..., 35-n when the addresses are coincident. An OR section 36 provides an output of a latch timing signal used to decide by which data latch section among the plural data latch sections 35-1, 35-2, ..., 35-n data are latched based on control information sets S1 , S2 , ..., Sn outputted from a communication serial signal WE. The data latch sections 35-1, 35-2, ..., 35-n receiving a valid latch timing signal latch parallel data outputted from the communication serial signal reception section 33. |
