NOTES:
1. 0-MHz operation is guaranteed when the STPCLK# and Stop Grant bus cycle protocol is used.
2. Not 100% tested, guaranteed by design characterization.
3. A reset pulse width of 15 CLK cycles is required for warm resets (RESET or SRESET). Power-up resets (cold resets)
require RESET to be asserted for at least 1 ms after V
CC
and CLK are stable.

NOTES:
1. TCK period
≤
CLK period.
2. Rise/Fall times are measured between 0.8V and 2.0V. Rise/Fall times can be relaxed by 1 ns per 10-ns increase in TCK
period.
3. Parameters t
30 –
t
37
are measured from TCK.
