3.1.2 Setting mask option with DIP-SW
the mask option resistor to these pins is specified by the DIP switch on IE-780208-R-EM in 1 bit units. The connection

P8 through P12 also serve as FIP pins (-40 V), and FIP0 through FIP12 are used as FIP pins. Therefore, connecting
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.
Note: When using IE-78000-R and IE-780208-R-EM, 5 V must be supplied to the target system (as the supply
