SPI Bus Timing
All timing diagrams use the following schematics and abbreviations:
H: Signal is high (logical
‘
1
’
)
L: Signal is low (logical
‘
0
’
)
X: Don
’
t care
Z: High impedance state (-> = 1)
*: Repeater
Busy: Busy token
Command: Command token
Response: Response token
Data block: Data token
All timing values are defined in Table
“
Timing Values
”
. The host must keep the clock running for at least
N
CR
clock cycles after receiving the card response. This restriction applies to both command and data
response tokens.
