Figure 5 Read Timing (S-29U394A)
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 low. A start-bit can only be recognized when the high of DI is latched at the rising
edge of SK after changing CS to low, it is impossible for it to be recognized as long as DI is low, even if there are SK
pulses after CS goes low. Instruction finishes when CS goes high, where it must be high between commands during
t
CDS
.
All input, including DI and SK signals, is ignored while CS is high, which is stand-by mode. The start bit + instruction,
address, and data are 8-bit instructions. This makes it easy to prepare your own software using a serial interface
incorporated into the CPU.
1.
READ
The READ instruction reads data from a specified address. After A0 is latched at the risig edge of SK, 16-bit
data is continuously output in synchronization with the falling edge of SK.
When all of the data (D
15
to D
0
) in the specified address has been read, data in the next address can be read
with the input of another SK clock. Thus, the data over whole area of the memory can be read by continuously
inputting SK clocks as long as CS is low.
The last address (An
A1 A0 = 1
11) rolls over to the top address (An
A1 A0 = 0
00).
