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
response tokens.
Command/Response
• Host Command to Card Response - Card is ready
• Host Command to Card Response - Card is busy
