Driver types and requirements for the signal pull- up and down are as follows. Resistor requirement is minimum for the 

host. - IO16 is pulled up in the drive with certain value so that the Vol is obtained to run with a host that has large value of 

pull up resistor.    - CS0    and - CS1 are also pulled up for better noise immunity.
