application. NMI input is also disabled in the error protection state and while the P or E bit
remains set in FLMCR1 during flash memory emulation in RAM.
Notes: 1. This is the interval until a branch is made to the boot program area in the on-chip RAM
(This branch takes place immediately after transfer of the user program is completed).
Consequently, after the branch to the RAM area, NMI input is enabled except during
programming and erasing. Interrupt requests must therefore be disabled inside and
outside the MCU until the user program has completed initial programming (including
the vector table and the NMI interrupt handling routine).
2. The vector may not be read correctly in this case for the following two reasons:
• If flash memory is read while being programmed or erased (while the P bit or E bit
is set in FLMCR1), correct read data will not be obtained (undetermined values will
be returned).
• If the entry in the interrupt vector table has not been programmed yet, interrupt
exception handling will not be executed correctly.
19.10 Flash Memory PROM Mode
The H8/3062F-ZTAT A-mask version has a PROM mode as well as the on-board programming
modes for programming and erasing flash memory. In PROM mode, the on-chip ROM can be
freely programmed using a general-purpose PROM writer that supports the Hitachi
microcomputer device type with 128-kbyte on-chip flash memory.
19.10.1 Socket Adapters and Memory Map
In PROM mode using a PROM writer, memory reading (verification) and writing and flash
memory initialization (total erasure) can be performed. For these operations, a special socket
adapter is mounted in the PROM writer. The socket adapter product codes are given in table
19.11. In the H8/3062F-ZTAT A-mask version PROM mode, only the socket adapters shown in
this table should be used.
