Internal Pullup Issue in MPC5744P

[hityouxinxin]

Hello:

   There is a question when I use MPC5744P,I want to use internal pullup on PB[13],but I failed.

   When I try to set PUE and PUS bit in MSCR register,it always 0.In RM,I found this table,the NA means PB[13] could not using internal PUS?

Hi,

yes, that is correct. On B[13] there is no pulup available as table 4-16 describes.

As you can see it is connected to ADC1_AN[0] channel by default.

regards,

Peter
