2. PARALLEL CONTROL INTERFACE
Access to the registers is provided through a nonmultiplexed parallel port. The data bus is 8 bits wide; the
address bus is 4 bits wide. Control registers are accessed directly; memory for long repetitive patterns is
accessed indirectly. RCLK and TCLK are used to update counters and for all rising edge bits in the
register map (RSYNC, LC, TL, SBE). At slow clock rates, sufficient time must be allowed for these port
operations.
