Command and response timings
All timing diagrams use the following schematics and abbreviations:
The difference between the P-bit and Z-bit is that a P-bit is actively driven to HIGH by the card
respectively host output driver, while the Z-bit is driven to (respectively kept) HIGH by the pull-up
resistors R
CMD
respectively R
DAT
. Actively-driven P-bits are less sensitive to noise superposition.
For the timing of the R0008 the following values are defined:
12:9
CURRENT_STATE
S X
0 = idle
1 = ready
2 = ident
3 = stby
4 = tran
5 = data
6-15 = reserved
Current state of the card.
