Notes on using the on-chip emulator (E10T) installed in the H8/3048F-ONE
H8/3048 Group products and H8/3048B Group products have different specifications regarding
the pin arrangement (pin 1, VCL), flash memory, and maximum operating frequency. Refer to
Comparison of H8/3048 Group Product Specifications for details of these differences.
Notes:
When using an on-chip emulator (E10T) for H8/3048 program development and debugging, the
following restrictions must be noted.
1. Only programs in the on-chip flash memory can be developed and debugged. Consequently,
emulation is not possible for programs in external memory or in the no-ROM mode.
2. Refresh controller and DMAC operation are not supported, so settings should not be made to
the registers for these modules.
3. During break mode of on-chip emulation, the watchdog timer stops counting. Accordingly, the
counter value may be invalid after resuming from the break mode.
4. The FWE (BRK) pin and pins P91, P93, and P95 are reserved for the E10T, and cannot be
used.
5. Area H'F7000 to H'F7FFF in 1-M address mode (area H'FF7000 to H'FF77FF in 16-M address
mode) is used by the E10T, and is not available to the user.
6. The initial program instructions following a reset should be initialize stack pointer (SP) and
read mode register (MDCR). (After initializing SP using the MOV.L instruction, use the
MOV.B instruction to read the MDCR register.)
7. Emulation of the hardware standby mode is not supported.
