(5) Runaway provision with ROM protection register
program, INTP1 is occurred and detects runaway function.
program ROM are as follows on the logical address memory map.
with EMCCR3<ENFROM, ENDROM, ENPROM>. And INTP1 interruption occurred
with which ROM area in the case that occurred can confirm each with
EMCCR3<FFLAG, DFLAG, and PFLAG>. This flag is cleared when write in 0.
(Purpose)
Provision in runaway of program by noise mixing.
(Operation explanation)
When writes operation was executed for external three kinds of ROM by runaway of
Three kinds of ROM is fixed as for flash ROM (Option program ROM), data ROM,
1. Flash ROM: Address 400000H to 7FFFFFH
2. Data ROM: Address 800000H to BFFFFFH
3. Program ROM: Address C00000H to FFFFFFH
For these address, admission/prohibition of detection of write operation sets it up
