6. Selecting the Clock
With the M32173T-PTC, it is possible to select the clock
supply to the MCU by the clock select switch (SW1). Select
the clock supply as shown below.
However, when using the M32173T-PTC, the clock cannot
be supplied from the target system.
10 MHz:
Supplies the clock (X1: 10 MHz) on the M32173T-
PTC board to the MCU.
SOCKET: Supplies the clock to the MCU from the socket
(X2) for mounting the oscillator on the M32173T-
PTC board. By mounting the oscillator to the X2
socket of the MCU, it is possible to change the
operating frequency.
For more details on the connecting the X2 socket
and the MCU, see Figure 4 (right).
5. Connection Procedure
The procedure for connecting the M32173T-PTC is shown
below.
(1) Mount the NQPACK144SD.
(2) Mount the YQPACK144SD on the NQPACK144SD.
(3) Secure the four corners of the YQPACK144SD with the
YQ-GUIDE's.
(4) Set the clock select switch.
For details, refer to "6. Selecting the Clock" shown
below.
(5) Connect the probe of the emulation pod and the M32173T-
PTC via the SDI MCU control interface cable and the
SDI trace interface cable.
(6) Mount the M32173T-PTC on the YQPACK144SD.
