serial data output [SQ(n)]
On a device having a serial data access port, the pins that serve as serial data output(s) when in the read mode. When the device or the serial port is not selected or enabled, the output(s) are in a floating (Z) state. When the numbering of the serial data outputs is significant for device operation, the serial data outputs are numbered beginning with 0.
