Hi
I have two questions.
1)-What is the pull up / pull down resistor value by default? Should we consider, in the power sequence, can we assume the default resistor is attached with respect to it the microcontroller pins.
2)-EMIF clock is used in asynchronous/synchronous. What is the default value of EMIF clock used in the asynchronous communication? How is it calculated.
Regards;
Hello Raheel,
1)-What is the pull up / pull down resistor value by default? Should we consider, in the power sequence, can we assume the default resistor is attached with respect to it the microcontroller pins.
We do not specify the internal pulls with respect to resistance. We refer to them with respect to their pull strength. Most of the pulls implemented in our devices are 20uA but this is pin dependent. Check the terminal function table within the datasheet for the pins you are interested in. After reset, the values and pull directions listed in the terminal functions table will be enabled.
2)-EMIF clock is used in asynchronous/synchronous. What is the default value of EMIF clock used in the asynchronous communication? How is it calculated.
EMIF clock is something that is configured during boot up (EMIF_CLK=VCLK3). VCLK3 is scaled from HCLK same as VCLK1. As a default it will be VCLK3/2 (i.e., VCLK3R+1 is the prescalar)..
