CHAPTER 3 INSTALLATION 3.2 Clock Settings 3.2.1 Overview of clock settings The main system and subsystem clocks to be used during debugging can be selected from (1) to (3) below. (1) Clock that is already mounted on emulation board (2) Clock that is mounted by user (3) External clock If the target system includes an internal clock, select either (1) Clock that is already mounted on emulation board or (2) Clock that is mounted by user.
CHAPTER 3 INSTALLATION (1) Clock that is already mounted on emulation board (a) For main system clock A crystal oscillator (X1) is already mounted on the emulation board. Its frequency is 10.0 MHz. Figure 3-5.
CHAPTER 3 INSTALLATION (2) Clock that is mounted by user The user is able to mount any clock supported by the set specifications on the IE-780338-NS-EM1. (a) For main system clock Remove the crystal oscillator (X1) that is already mounted on the emulation board, and mount either the parts board on which the resonator to be used is mounted or an oscillator. This method is useful when using a different frequency from that of the pre-mounted clock. Figure 3-7.
CHAPTER 3 INSTALLATION (3) External clock An external clock connected to the target system can be used via an emulation probe. Figure 3-9. When Using an External Clock IE-78K0-NS or IE-78K0-NS-A Target system IE-780338-NS-EM1 Emulation probe Clock generator (to be used) Remark The clock supplied by the target system’s clock generator (encircled in the figure) is used. 3.2.2 Main system clock settings Table 3-1.
CHAPTER 3 INSTALLATION (2) When using clock mounted by user Execute the settings described under either (a) or (b), depending on the type of clock to be used. When starting the integrated debugger (ID78K0-NS), open the configuration dialog box and select “Internal” in the area (Clock) for selecting the CPU clock source (this selects the emulator internal clock).
