(4) MCU Clock Frequency [FUNC DF]
Set up the input clock frequency of the target microcomputer.
Programmer refers this value when executing the device function to determine the baud rate
with microcomputer. If this is not set correctly, the communication between the programmer and
microcomputer is not established.
For setting clock frequency for NET IMPRESS, see the NETIMPRESS next Instruction Manual
at section 5.4.12. “MCU Operating Frequency Setting”.
Note: The operation clock for the target microcomputer is calculated using this value and the
setting value of Parameter Table 2.
For detail, see the section 2.2.4. Setting Up Multiplication and Clock Division
.

(6) WDT Clock Period [FUNC D5]
NET IMPRESS has the function to output periodic clock pulses during programming. To use
this function, it is required to setup the WDT Clock Period.
The periodic clock pulse is output from the WDT signal (No. 18 pin) that is listed in the target
probe list of section 3.1 “Signal List”.
For the operation procedure to set up WDT on NETIMPRESS main unit, see the
NETIMPRESS next Instruction Manual at section 5. 4. 7 “Watchdog Timer Setting”.
