CHAPTER 4 4.1 CAUTIONS VDD and PORTVDD of Target System (1) VDD in the target system is used to sense the level for target system power supply ON/OFF. • When VDD is lower than 3.5 V, it is judged that the target system is not connected, and mapping of the target memory cannot be performed with a debugger (FCAN cannot be used). • When VDD is 3.5 V or higher, it is judged that the target system is connected, and mapping of the target memory can be performed with a debugger (FCAN can be used).
CHAPTER 4 CAUTIONS (3) The VDD1 signal from the target system is left open in the IE-703089-MC-EM1. (4) The following conditions must be satisfied when other than VDD0 = VDD1 = ADCVDD = PORTVDD1 = PORTVDD2. 1. When FCAN is used, PORTVDD1 ≤ PORTVDD2 (restricted by the power supply voltage conditions of the incircuit emulator) 2. When ADC is used, VDD0 = ADCVDD = 4.5 to 5.5 V 4.
CHAPTER 5 DIFFERENCES BETWEEN TARGET DEVICE AND TARGET INTERFACE CIRCUIT Differences between the signal lines of the target device and the signal lines of the IE-703089-MC-EM1 target interface circuit are described in this chapter. The target device is a CMOS circuit, whereas the target interface circuit of the IE-703089-MC-EM1 is configured with an emulation circuit such as a gate array TTL or CMOS-IC.
