6020. MXSYNC# is used by the CPCI-6020-MCPTM-01 to synchronize with the CPCI-6020
module. MXDO is the time-multiplexed output line from the CPCI-6020 and MXDI is the time-
multiplexed line from the CPCI-6020-MCPTM-01. A 16-to-1 multiplexing scheme is used with
10 MHz bit rate. Sixteen time slots are defined and allocated as follows:
