2, 3
Modified Note 12 to correct tREC operation.
6
Added various conditions text to TOCs 1, 2, and 3.
7
Added text to pin descriptions for 32kHz, VCC, and
RST.
9
Table 1: Changed column heading “Powered By” to “Active Supply”; changed
“applied” to “exceeds VPF” in the Power Control section.
10
Indicated BBSQW applies to both SQW and interrupts; simplified temp convert
description (bit 5); added “output” to
INT/SQW (bit 2).
13
4
10/06
