Remarks: When emulating PD78024 Series, the target of mask option to be set with DIP-SW will be FIP0 to FIP25.
3.2 Target Interface Circuit
R. It consists of an emulation device and various gates (ICs, such as CMOS and TTL).

when the emulation device signals are input/output through gates.
a gate. This is responsible for the differences in the AC characteristics.

Caution: When using IE-78000-R and IE-78044-R-EM, 5 V must be supplied to the target system (as the
P8 through P12* also serve as FIP pins (-40 V). Connecting the mask option resistor to these pins is specified by
The target interface circuit allows the device to operate in the same manner as the target device on the IE-78000-
To debug the target system connected to IE-78000-R, emulation is carried out by the target interface circuit in IE-
Individual target devices consist of CMOS LSIs. The target interface circuit emulation device also consists of CMOS
However, the DC and AC characteristics for the target interface circuit are different from those for the target device,
Note that, a gate delay time (whose duration varies, depending on the gate) occurs each time the signal goes through
Therefore, design the target system, giving thorough consideration to these points.
PD78024 Subseries is not provided with P12.
