CP 6/1

STLC5460

Comparison 6 to 1.

Bit stream of one PCM and bit stream of another PCM are compared at each bit time, if

there is difference, PDIF interrupt is generated.

CP1 = 1

CP2 = 1

CP3 = 1

CP4 = 1

CP5 = 1

CP6 = 1

CIM

Command/Indicate Mode.

CIM = 1: the controller ignores the new received primitive if the previous has not been

read by the microprocessor.

MOM

CI4M1

CI4M0

GCIM1

GCIM0

CIM = 0: the controller overwrites the previous primitive without condition when it

receives a new primitive.

Monitor channel Mode

MOM = 1: if bytes are not received twice identical the message is aborted.

MOM = 0: if bytes are not received twice identical the MOM controller doesn’t

acknowledge the received byte (GCI standard).

Command Indicate 4 bits for Multiplex 1.

CI4M1 = 0: command Indicate primitive has six bits.

CI4M1 = 1: command Indicate primitive has four bits.

Command Indicate 4 bits for Multiplex 0.

CI4M0 = 0: command Indicate primitive has six bits.

CI4M0 = 1: command indicate primitive has four bits.

GCI Multiplex 1.

GCIM1 = 1: the multiplex M1 is GCI, it includes eight GCI channels.

GCIM1 = 0: the multiplex M1 includes 32 Time Slots. (PCM like channel)

GCI Multiplex 0.

GCIM0 = 1: the Multiplex M0 is GCI, it includes eight GCI channels.

GCIM0 = 0: the multiplex M0 includes 32 Time Slots. (PCM like channel)

M1D = 1. Multiplex 1 output is at high impedance continuously,

multiplex 1 input is forced to ”1”, if it is GCI.
