with sub-board the emulation cpu of t he IE-789468-NS-EM1 to be used differs dependi ng on the target subseries device. the pd78f9328gk, which is t he emulation cpu (i/o eva chip) used for debugging a pd789327/179327 subseries device, is set at shipment. there is no need to change any hardware settings when using the factory settings. when debugging a pd789467 subseries device, remove the cn board mounted between cn101 and cn102, and attach it between cn102 and cn103. this changes the target em ulation cpu to the pd78f9468gk, which is the emulation cpu (i/o eva chip) for debugging a pd789467 subseries device. figure 3-1. changing emulation cpu for IE-789468-NS-EM1 with sub-board cn board attached at shipment attach remove cautions 1. be sure to align the pin number (position of pin 1) when attaching the cn board. 2. changing of the emulation cpu must be ca rried out after the power supply to the ie-78k0- ns or ie-78k0s-ns-a has been switched o ff. changing the emulation cpu during power- on may damage the ie system. chapter 3 installation user?s manual u16482ej1v0um 20 (2) settings for the IE-789468-NS-EM1 without sub-board the emulation cpu of t he IE-789468-NS-EM1 to be used

supply to the ie- 78k0s-ns or ie-78k0s-ns-a has been switched off. replacing the emulation cpu during power-on may damage the ie system. 2. be sure to align pin 1 of the emulation cp u (i/o eva chip) to the position of pin 1 of the socket (ic1) when mounting the emulation cpu. mounting the emulation cpu (i/o eva chip) misaligning the pin 1 position may damage the emulation cpu. 3. the emulation cpu (i/o eva chip) may not ope rate normally if it is mounted with its pin leads bent. 4. check that the emulation cpu (i/o eva chip) does not have resin flash, broken or bent pins, or other problems before mount ing it on the nqpack080sb. when mounting the hqpack080sd on the nq pack080sb on which the emulation cpu is mounted, check that all holding pins of the hq pack080sd are not broken or bent. if the hqpack080sd has a bent pin, straighten it using a thin plate or a knife-like blade. chapter 3 installation user?s manual u16482ej1v0um 22 3.2 connection (1) connection with ie-78k0s-ns or
