ENA1
SSI Enable Strobe/ST-BUS & GCI Mode for Rin/Sout (Input). This pin
has dual functions depending on whether SSI or ST-BUS/GCI is selected.
For SSI, this strobe must be present for frame synchronization. This is an
active high channel enable strobe, 8 or 16 data bits wide, enabling serial
PCM data transfer for on Rin/Sout pins. Strobe period is 125 ms. For ST-
BUS or GCI, this pin, in conjunction with the MD1 pin, selects the proper
mode for Rin/Sout pins (see ST-BUS and GCI Operation description).
245
MD1
ST-BUS & GCI Mode for Rin/Sout (Input). When in ST-BUS or GCI
operation, this pin, in conjunction with the ENA1 pin, will select the proper
mode for Rin/Sout pins (see ST-BUS and GCI Operation description).
Connect this pin to Vss in SSI mode.
346
ENA2
SSI Enable Strobe /ST-BUS & GCI Mode for Sin/Rout (Input). This pin
has dual functions depending on whether SSI or ST-BUS/GCI is selected.
For SSI, this is an active high channel enable strobe, 8 or 16 data bits wide,
enabling serial PCM data transfer on Sin/Rout pins. Strobe period is
125 ms. For ST-BUS/GCI, this pin, in conjunction with the MD2 pin, selects
the proper mode for Sin/Rout pins (see ST-BUS and GCI Operation
description).
447
MD2
ST-BUS & GCI Mode for Sin/Rout (Input). When in ST-BUS or GCI
operation, this pin in conjunction with the ENA2 pin, selects the proper
mode for Sin/Rout pins (see ST-BUS and GCI Operation description).
Connect this pin to Vss in SSI mode.
