19 / 38 page ![]() RM0345 Tool IO Doc ID 024080 Rev 3 19/38 7 Tool IO The SPC563M64xx in CSP496 package provides 2 signals, GPIO[206] & GPIO[207], that are not available in the QFP144 standard production package. They can be used by the calibration tools to implement triggers and handshakes. On the calibration board, these signals are available on the JP1 development connector and J9 calibration connector. By default GPIO[206] & GPIO[207] are powered by VDDEH at 5V. A level shifter (see Figure 11) does the translation between the 5v and the 3.3V. This is because the calibration tools operates at 3.3V that is the voltage level of the JTAG and Nexus interfaces. Figure 11. Calibration triggers TOOL_IO |
