Flash Interrupt Control Register
There are two sources of interrupts from the Flash controller. These two sources are:
•
•
Either or both of the two interrupt sources can be enabled by setting the appropriate bits in
the Flash Interrupt Control register.
The Flash Interrupt Control register contains four status bits to indicate the following error
conditions:
•
•
•
•
If the Error Condition Interrupt is enabled, any of the four error conditions result in an
interrupt request being sent to the eZ80F92 device’s Interrupt Controller. Reading the
Flash Interrupt Control register clears all error condition flags and the done flag.

Row Program Time-out
current Row Program operation does not complete within 2,432 Flash controller
clocks (12.4–15.8 ms depending on the Flash controller clock period), the Flash con-
troller terminates the Row Program operation by clearing Bit 2 of the Flash Program
Control register and setting the RP_TMO error bit to 1.
Write Violation
memory (the Write is not performed).
Page Erase Violation
memory (the requested page is not erased).
Mass Erase Violation
more protected blocks in Flash memory (the Mass Erase is not performed).
