Data Sheet
Guaranteed by design; not subject to production test.
See the Timing Diagrams section for the location of measured values.
Typicals represent average readings at 25°C and V
Propagation delay depends on the value of V
Valid for commands that do not activate the RDY pin.
RDY pin low only for Command Instruction 2, Command Instruction 3, Command Instruction 8, Command Instruction 9, Command Instruction 10, and the PR hardware pulse:
CMD_8 ~ 1 ms, CMD_9 = CMD_10 ~ 0.12 ms, and CMD_2 = CMD_3 ~ 20 ms. Device operation at T
