04/17/12
R. Willner
1. Change description for SDAT and SCLK pins.
2. Add new footnotes to pin descriptions table
3. Added section "Crystal Clock Selection"
4. Added logic diagram and Truth table for "SD/OE Pin Function" section.
5. Corrected register readback values for 0x52~0x54 and 0x7C~0x7F.

L
06/04/12
A. Tsui
1. Updated SD-OE pin description; from (Default is active HIGH) to (Default is active
LOW)
2. Updated “OUTn” column in Truth Table with “High-Z” specs and added footnote 2,
“High-Z regardless of OEM bits”.
3. Updated “SD-OE Pin Function” section to reflect that SP is “0”changed from active
HIGH to active LOW, and SP is “1” changed from active LOW to active HIGH.
M
