10.3.3 Signal Treatment
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. | |||||
