3.2 ROM on Target System
The following describes the pin assignment of the ROM probe (sold separately) and cautions when connecting the
target system using the ROM probe.
3.2.1 ROM connector
Figure 3-4 shows the pin assignment of the ROM probe (sold separately).
The ROM probe (sold separately) supports ROM with two types of pin layouts.

Remarks 1. The pin assignment of the EP-16000C (sold separately) is equivalent to that of the
27C4000/27C8000/27C16000, except for pin 32, which is an NC pin.
2. The pin assignment of the EP-16384C (sold separately) is equivalent to that of the 27C4096 for
pins from 2 to 41, but pin 2 is an NC pin. Note that the pin assignments of pins 1 and 42 are
exclusive to the EP-16384C (sold separately).

3.2.2 ROM probe setting
Figure 3-5 shows the jumper setting of the ROM probe.
The ROM probe supports 3.3 V ROM and 5 V ROM, so set the jumper in accordance with the voltage of the ROM
to be mounted on the target system.
Figure 3-5. Voltage Setting of ROM Probe (EP-16000C (Sold Separately) and EP-16384C (Sold Separately))
1 and 2 shorted: When the voltage of the ROM on the target system is 3.3 V
2 and 3 shorted: When the voltage of the ROM on the target system is 5 V (factory setting)

The interface circuit of the ROM probe is shown in Figure 3-6.

Cautions 1. The bus load of the target system when the ROM probe is connected may be higher than
that when an actual ROM is connected. Caution must be paid when designing the bus of
the target system. It is recommended to mount a bus buffer in the ROM of the target
system.
2. A18 and A19 are pulled down (50 kΩ) inside the ROM probe, so they must be NC (no
connection) on the target system when they are not used on the target system.
3. When using the ROM emulation function, set the size of the ROM area set by the mapping
command of the debugger to the same size as the size of the ROM on the target system.
If these settings are different, the ROM emulation memory cannot be read with a correct
address from the target device.
4. Data cannot be written to the ROM emulation memory form the target device.
5. The access time of the ROM emulation memory is 60 ns. Set the wait count of the target
device to an appropriate value when using the ROM emulation memory.
