Operation
Instructions (in the order of start-bit, instruction, address, and data) are latched to DI in synchronization with the rising
edge of SK after CS goes high. A start-bit can only be recognized when the high of DI is latched to the rising edge of SK
when CS goes from low to high, it is impossible for it to be recognized as long as DI is low, even if there are SK pulses
after CS goes high. Any SK pulses input while DI is low are called "dummy clocks." Dummy clocks can be used to
adjust the number of clock cycles needed by the serial IC to match those sent out by the CPU. Instruction input finishes
when CS goes low, where it must be between commands during t
CDS
.
All input, including DI and SK signals, is ignored while CS is low, which is stand-by mode.
1. Read
The READ instruction reads data from a specified address. After A0 is latched at the rising edge of SK, DO output
changes from a high-impedance state (Hi-Z) to low level output. Data is continuously output in synchronization with the
rise of SK.
When all of the data (D15 to D0) in the specified address has been read, the data in the next address can be read
with the input of another SK clock. Thus, it is possible for all of the data addresses to be read through the continuous
input of SK clocks as long as CS is high.
The last address (An
A1 A0 = 1
11) rolls over to the top address (An
A1 A0 = 0
00).
