4 0 SONIC-16 Registers
Note 1 These registers can only be read when the SONIC-16 is in reset mode (RST bit in the CR is set) The SONIC-16 gives invalid data when these registers are
read in non-reset mode
Note 2 This register can only be written to when the SONIC-16 is in reset mode This register is normally only loaded by the Load CAM command
Note 3 The Data Configuration registers DCR and DCR2 can only be written to when the SONIC-16 is in reset mode (RST bit in CR is set) Writing to these
registers while not in reset mode does not alter the registers
Note 4 The data written to these registers is inverted before being latched That is if a value of FFFFh is written these registers will contain and read back the
value of 0000h Data is not inverted during a read operation
Note 1 The data that is read from these registers is the inversion of what has been written to them
Note 2 The value that is written to this register is shifted once
