(7) Data Communication
This is the field to make communication settings between NET IMPRESS and the target
microcomputer.
For FR830, make complete settings as follows.
・
Selection of communication channel [FUNC D 1]
Choose UART (Asynchronous communication) or CSI (Synchronous communication).
For the operation procedure to set up communication channel on NETIMPRESS main unit,
see the NETIMPRESS next Instruction Manual at section 5. 4. 2 “Communication Channel
Setting”.
・
Channel No. [FUNC D7]
Select one-wire or two-wire mode when you select UART (Asynchronous communication).
TGT CHANNEL 0: two-wire mode
TGT CHANNEL 1: one-wire mode
・
UART Baud Rate [FUNC D2]
Set the baud rate for UART communication.
Select from 2400 / 4800 / 9600 / 19200 / 31250 / 38400 / 62500 / 76800 / 10400 / 115200 /
125000 / 153600 / 230400 / 250000 / 307200 / 460800 / 500000 / 614400 / 1000000 /
2000000 bps.
For the procedure of setting the UART baud rate on NET IMPRESS main unit, see the
NETIMPRESS next Instruction Manual at section 5.4.3. “UART Baud Rate Setting”.
When you use the baud rate higher than 115200 bps with a programmer other than
NETIMPRESS next, see the section 2.2.5. “High Speed UART Baud Rate Setting”
in
this manual.
For two-wire UART, 1000000/2000000 bps is available for NET IMPRESS next (AF430
Rev.C or later (HARD VER 40.04 or later,
HARD2 VER 40.26 or later)) only.
For one-wire UART, 1000000/2000000bps is available for NET IMPRESS next (AF430 or
later (HARD VER 40.05 or later, HARD2 VER 40.28 or later)) only. Also, when
1000000/2000000 bps is set for one-wire UART, TTXD signal is open drain output.
・
CSI Baud Rate [FUNC D9]
Set the baud rate for CSI communication.
Select from 62.5K/125K/250K/500K/850K/1.25/2.5M/3.3M/5M bps.
For the procedure of setting the CSI baud rate on NET IMPRESS, see NETIMPRESS next
Instruction Manual at section 5.4.4. “CSI Baud Rate Setting”.
