(3)Replacing the Oscillator Circuit Boards

Figure 3.14 shows how to replace the oscillator circuit boards. For the position of the oscillator circuit

board, see "Figure 2.2 Internal view of the emulation pod" (page 21).

Figure 3.14 Replacing the oscillator circuit boards

(1) Unscrew the screw connecting the oscillator circuit

board.

(2) Lift off the oscillator circuit board.

(3) Attach the J1 connector of another oscillator circuit

board for replacement to the connectors J5 (XCIN) or

J6 (XIN) of the MCU-dependent board M37641T-

RPDM.

(4) Secure the oscillator circuit board to the MCU-

dependent board M37641T-RPDM with the screw.
