SRC4192 Handling for the Mode Setting Pins

Sadanori Kato

Other Parts Discussed in Thread: SRC4192

Hi,

Could you please tell us the handling for the mode setting pins ?

<Mode Setting Pins>
LGRP
BYPAS
IFMT0/1/2
OWL0/1
OFMT0/1
TDMI
MODE0/1/2

Q1. Internal Pull-down/up Resistors
Is our understanding correct although it seems that these pins don't have the internal pull-down/up resistors ?
Could you please tell us the value of these resistors if these pins have them ?

Q2. Connecting These Pins to VIO or DGND Directly
Is our understanding correct although we believe that these pins are able to be connected to VIO or DGND directly such as SRC4192 evm?

Best regards,
Kato

Hi, Kato-san,

Those pins do not have internal pull-up/downs.

You may directly connect them to VIO or DGND as needed.

The specifications for the pins is on page 4 of the d/s:

Hi Don-san,

Thank you for your reply even though you are busy.
I have an additional question.
Is my understanding correct although I believe that the input type is CMOS ?

Best regards,
