5.2.2.1
The long write is what actually programs words of data
into the internal memory. When a TBLWT to the MSB of
the write block occurs, instruction execution is halted.
During this time, programming voltage and the data
stored in internal latches is applied to program memory.
For a long write to occur:
1.
2.
3.
If the LWRT bit is clear, a short write will occur and pro-
gram memory will not be changed. If the TBLWT is not
to the MSB of the write block, then the programming
phase is not initiated.
Setting the LWRT bit enables long writes when the
MCLR pin is taken to V
is set, it can be cleared only by performing a POR or
MCLR Reset.
To ensure that the memory location has been well pro-
grammed, a minimum programming time is required.
The long write can be terminated after the program-
ming time has expired by a RESET or an interrupt.
Having only one interrupt source enabled to terminate
the long write, ensures that no unintended interrupts
will prematurely terminate the long write.
