53 / 130 page ![]() 53/130 STLC5466 The New Primitive is taken into account by the transmitter after writing bits 8 to 15 (if 8bit microprocessor). Transmit Command/Indicate Register (after reading) When this register is read by the microprocessor, these different bits mean: VI.23 - Transmit Monitor Address Register TMAR (2C)H When this register is written by the microprocessor, these different bits mean: bit15 bit8 bit7 bit0 D=0 G0 CA2 CA1 CA0 READ Nu Nu PT1 PT0 C6 C5 C4 C3 C2 C1 D=1 G0 CA2 CA1 CA0 READ Nu Nu PT1 PT0 A E S1 S2 S3 S4 READ : READ C/I MEMORY READ = 1, READ C/I MEMORY. READ = 0, WRITE C/I MEMORY. CA 0/2 : TRANSMIT C/I ADDRESS CA0/2: These bits define one of eight Command/Indicate Channels. G0 : This bit defines one of two GCI multiplexes. G0 = 0, TDM4 is selected. G0 = 1, TDM5 is selected. D : Destination. This bit defines the destination of bits 0 to 5. D=0: the destination is a GCI channel defined by G0 and CA0/2. D=1:the destination is any TDM (after switching). C6/1 : Last Primitive transmitted. Case of D=0 A, E, S1 to S4 : 6 bit word transmitted. Case of D=1. PT0/1 : Status bits bit15 bit8 bit7 bit0 0 G0 MA2 MA1 MA0 READ Nu Nu Nu Nu TIV FABT L NOB 0 Nu After reset (000F)H READ : READ MON MEMORY READ=1, READ MON MEMORY. READ=0, WRITE MON MEMORY. MA 0/2 : TRANSMIT MONITOR ADDRESS MA 0/2:These bits define one of eight Monitor Channel if validated. G0 : This bit defines one of two GCI multiplexes. G0 = 0, TDM4 is selected. G0 = 1, TDM5 is selected. NOB : NUMBER OF BYTE to be transmitted NOB = 1, One byte to transmit. NOB = 0, Two bytes to transmit. P1 P0 Primitive Status 0 0 Primitive has not been transmitted yet. 0 1 Primitive has been transmitted once. 1 0 Primitive has been transmitted twice. 1 1 Primitive has been transmitted three times or more. |
