11 / 47 page ST8012 V1.6 11/47 2004/09/08 (common /segment mix mode) ElO1, EIO2 Input/output pins for chip selection AT common/segment mode: When L/R input is at Vss level “L”, ElO1 is set output, and EIO2 is set for input. ElO1 : segment chip enable output, as default segment is enabled internally and be non-selected after 8,24,40,56,72 or 88 bits of data have been read. Depend on select mode. ElO2 :common shift data input, no sift data output When L/R input is at VDD level "H", ElO1 is set for input, and EIO2 is set for output. ElO1 :common shift data, no shift data output ElO2 : segment chip enable output, as default segment is enabled internally and be non-selected after 8,24,40,56,72 or 88 bits of data have been read. Depend on select mode. During output, set to "H" while LP • XCK is "H" and after 120 bits of data have been read, set to "L” for one cycle (from falling edge to failing edge of XCK), after which it returns to "H". During input, the chip is selected while El is set to "L" after the LP signal is input. The chip is non-selected after 120 bits of data have been read. |
