4 0 SONIC-16 Registers
4 2 STATUS CONTROL REGISTERS
This set of registers is used to convey status control infor-
mation to from the host system and to control the operation
of the SONIC-16 These registers are used for loading com-
mands generated from the system indicating transmit and
receive status buffering data to from memory and provid-
