Dears.
I understood that each one port consists of 8 IO pins and each IO Pin is mapped with GPIO_PRT_CFG_IN.VTRIP_SEL to configures the GPIO pin input buffer voltage threshold mode. For example, PORT 0 consists of 8 IO PINs and in order to configure that input buffer of Port 0_Pin 7 is compatible with TTL, I should set 0x01 in GPIO_PRT_CFG_IN.VTRIP_SEL7_0. Correct ?
If it’s correct, I couldn’t find the VTRIP_SEL7_0 in GPIO_PRT_CFG_IN, only i can see the lower 4bits are available. Could you give me your opinion ?
Additionally, would you tell me what "S40S", "S40E" and "S40" mean?
Best regards,
Kevin Han.

Hello Kevin,
These pins are available on 176-LQFP and 144-LQFP pin packages (attachment) and GPIO_PRT7_CFG_IN can be configured.
Please let us know which pin package you are using. You can find that information under 'Part Number Nomenclature' section of the device datasheet.
And "S40S", "S40E" and "S40" are different technologies, it is unimportant to the user. These terms are used for internal purpose only.
Best regards,
Swathi

Hello Kevin,
Could you please specify the device MPN and which GPIO port you are using?

Hello Swathi.
MPN is CYT2B9 and Port 0_Pin 7
Thanks,
Kevin Han.

Hello Kevin,
Port 0_Pin 7 is not available on this device. Please refer to the 'pin assignment' section of the CYT2B9 device datasheet to check the availability of pins for your package.
Best regards,
Swathi

Hello Swathi.
Thank you for your answer.
How about P7.6 and P7.7 ? Are they possible to be configured as "TTL" or "Automotive"?
And What "S40S", "S40E" and "S40" mean?
Br,
Kevin Han.
