DLY7 Delay to Allow Self-Timed Data Write or
Bulk Erase to Occur
5—ms
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 T
CY + TPWRT (if enabled) + 1024 TOSC (for LP, HS, HS/PLL and XT modes only) +
2 ms (for HS/PLL mode only) + 1.5 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.
2: When ICPRT = 1, this specification also applies to ICV
PP.
3: At 0°C-50°C.
