(3) When pulse is input from target system
No hardware settings are required for this situation.
When starting the integrated debugger (ID78K0S-NS), open the configuration dialog box and select "External" in
the area (Clock) for selecting the CPU's clock source (this selects the user's clock).
3.4.3 Subsystem clock settings
The subsystem clock settings of the IE-789835-NS-EM1 are as shown in Table 3-5. The following shows the
respective IE-789835-NS-EM1 settings for the subsystem clocks used in (1) to (3) in Table 3-5.
Frequency of Subsystem Clock to Be Used
(1)
When using clock (XTC1)
that is already mounted
on emulation board
(2)
When using clock
mounted by user
(3)
When pulse is input from
target system
Caution
Jumper JP2, which is used to select the board's clock or an external clock, should be set only
after turning off the power of the IE-78K0S-NS or IE-78K0S-NS-A.
Remark When the IE-789835-NS-EM1 is shipped, the settings for "when using clock that is already mounted on
emulation board" are preset.
(1) When using clock that is already mounted on emulation board
When the IE-789835-NS-EM1 is shipped, a 32.768 kHz crystal resonator (XTC1) and the parts board (X2) on
which pins 6 and 8 are shorted are already mounted on the IE-789835-NS-EM1. Short the 2 to 3 side on the IE-
789835-NS-EM1's jumper (JP2). There is no need to make any other settings via the integrated debugger
(ID78K0S-NS).
(2) When using the clock mounted by user
The settings described under either (a) or (b) are required, depending on the type of clock to be used. Short the
2 to 3 side on the IE-789835-NS-EM1's jumper (JP2).
There is no need to make any other settings via the integrated debugger (ID78K0S-NS).
