Conditions
Note 1:
Do not allow excess time when transitioning MCLR between VIL and VIHH; this can cause spurious program
executions to occur. The maximum transition time is:
1 TCY + TPWRT (if enabled) + 1024 TOSC (for LP, HS, HS/PLL and XT modes only) + 2 ms (for HS/PLL mode only)
+ 1.5
渭s (for EC mode only) where TCY is the instruction cycle time, TPWRT is the Power-up Timer period and
TOSC is the oscillator period. For specific values, refer to the Electrical Characteristics section of the device data
sheet for the particular device.
