2-5. RESET Circuit
Fig.2-3 shows the reset circuit of the model.
When the pin-51 [XRST3] terminal of IC9001 becomes “Open” state, 3.3V voltage is supplied as the master reset signal, XRST, via the pull-up resistor, R6054. Then, 3.3V
voltage is supplied to ICs shown in Table.2-5 as AF_XRST signal via NOT IC6007 and IC6006.
