SC18IS602B Chip Select Function

[shubhatr_23]

 Hi,

I want to interface SC18IS602B with DAC AD5504. For this Chip Select has to toggle(low to high) after 16bits of data is transmitted. What is the behavior of Chip Select pin on SC18IS602B? Will it toggle from low to high after each data byte is transmitted or after all data bytes in the buffer (up to 200 bytes) are transmitted? There is no timing diagram given in the data sheet.

Thanks in advance.

Hi Thomas,

Thanks for the reply. It would be really helpful if you can share a timing diagram for the same.

Thanks.

Hi Shreya,

The SSx outputs on the SC18IS602B are all low-true. They all are high when idle and only one (the selected one) is low when transferring all the data - in your case 2 bytes. 

Best regards,

Tomas
