Hello
I am understanding that unused pins can be left unconnected.But , please let me know if there is any problem in the following cases.
Q1) If PORT4 is not used, is it okay to set the Fixed port (FIXED_PORT4: Pull up)?
Q2) If PORT4 is not used, should SET_PORT_NUM1 / 2 also be [NUM2: NUM1] = [0 (PD): 1 (PU)]?
Best Regards
Arai

Hi,
1) If PORT 4 is not used, you can leave FIXED_PORT4 NC.
2) Yes, when PORT_4 is not being used, configuring SET_PORT_NUM2 / 1 to 0:1 is fine.

Hello
Thank you for your reply.

I understand that if PORT4 is unused, it is okay to leaveFIXED_PORT4 unconnected.
However, when PORT4 is not used, I would like to know whether there is no problem even if the setting of FIXED_PORT4 is "pull up"?or not

Hello
From the contents of the answer, I understand that there is no problem with the following configuration when PORT4 is not used.
--leave FIXED_PORT4 NC.
--configuring SET_PORT_NUM2 / 1 to 0: 1
Q1) Is it okay to consider the above answer as a recommended setting?
Also, if the customer does not use PORT4, there is a question as to whether there is a problem with the following setting cases,too.
Q2) FIXED_PORT4: Pull up -- Is it okay to pull up? (When PORT4 is not used)
Q3 Is it okay to set SET_PORT_NUM2 / 1 to 0: 0? (When PORT4 is not used)
Best regards

Hello Arai-san,
1) Yes it is the recommended setting.
2) It is not fine to pull-up FIXED_PORT4 if PORT 4 is not used. Leave it floating.
3) Kindly refer to Table 3, Page 17 in the HX2VL datasheet for configuring SET_PORT_NUM2/1.
