6. Selecting a Clock
With the M32176T-PTC, it is possible to select a clock
supply to the MCU by the clock select switch (SW1). Select
a clock supply as shown below.
However, when using the M32176T-PTC, the clock cannot
be supplied from the target system.
10 MHz: Supplies a clock (X1: 10 MHz) on the M32176T-
PTC board to the MCU.
SOCKET: Supplies a clock to the MCU from the socket
(X2) for mounting an oscillator on the M32176T-
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 connecting the X2 socket and
the MCU, see Figure 4 (right).
5. Connection Procedure
The procedure for connecting the M32176T-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 a Clock" shown below.
(5) Connect the probe of the emulation pod and the M32176T-
PTC via the SDI MCU control interface cable and the
SDI trace interface cable.
(6) Mount the M32176T-PTC on the YQPACK144SD.
