XC878 UM 1.1 states in section 4.4:
[quote="XC878 UM 1.1"]The Flash Timer has 2 operating modes, Program Timer and Erase Timer modes, which
are selectable using the bit FTVAL.MODE. In Program Timer mode (FTVAL.MODE=0),
a 7-bit counter is used to count up to the designated overflow value stored in
FTVAL.OFVAL. Once this value is reached, the associated overflow flag FCS.FTOV is
set
.

But section 4.9 (Register Description) doesn't know about a bit named FTOV. I'd guess it's FCS.4. It also could be FCS.7. Is there an official answer?

A little update. After some testing I have come to the conclusion that the FTOV bit does not exist, or at least it is not located in the FCS register. However I just confirmed my first successful non-blocking flash write (0x23) to the address 0xf000, by using the NMIFLASH interrupt instead of polling for the timer.
