MODE SELECTION
POWER-UP TIMING
Note:
(1) The store operation has priority over all the other operations.
(2) The store operation is inhibited when V
(3) NOP designates that the device is not currently executing an instruction.
(4) This parameter is tested initially and after a design or process change that affects the parameter.
