HiI am using Renesas RA6M4 in my project.Regarding spec it seems to me that MCU pins during and immediately after a reset (respectively left unconfigured) operate as INPUT Hi-Z.My question regarding this reset/default configuration of IO pins: Is there a weak pull up resistor (13-24kOhm) electrically active in the internal design of the pin/pad structuresHope you can give me some advice on this issue.Best regardsChristian
Not unless you enable it using bit 4 of the FPS register.
see section 19.2.5 of the manual.
You can also enable it from the “pins” section of the configuration.xml
The actual spec is from 10kΩ…
The actual spec is from 10kΩ to 50kΩ, typically 20kΩ on RA4M1, but it is specified as a current between 10μΑ and 300μA on an RA6M4
see table 2.6 of the datasheet
Hi,thanks for answering that fast.I think everything is clear now.Many thanks for your remarks and support.RegardsChristian
