VIII - INTERNAL REGISTERS (continued)
VIII.22 - Transmit Command / Indicate Register - TCIR (2A)H
When this register is written by the microprocessor, these different bits mean :
READ : READ C/I MEMORY
CA 0/2 : TRANSMIT COMMAND/INDICATE MEMORY ADDRESS
G0
D
C6/1
A, E, S1 to S4: New 6 bit word to be transmitted into any output timeslot. Case of D=1.
The New Primitive (or the 6 bit word) 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 :
READ : READ C/I MEMORY
CA 0/2 : TRANSMIT C/I ADDRESS

G0
: This bit defines one of two GCI MULTIPLEXy.
: Destination; this bit defines the destination of bits 0 to 5.
G0
G0
: New Primitive to be transmitted to the selected GCI channel (DOUT4 or DOUT5). Case of D=0.
G0
G0
: This bit defines one of two GCI multiplexes.
: Destination. This bit defines the destination of bits 0 to 5
: Last Primitive transmitted. Case of D=1
READ = 1, READ C/I MEMORY.
READ = 0, WRITE C/I MEMORY.
CA 0/2 : These bits define one of eight Command/Indicate Channels.
G0 = 0, GCI0 (DIN4/DOUT4) is selected.
G0 = 1, GCI1 (DIN5/DOUT5) is selected.
D=0: the primitive C6 to C1 is transmitted directly into one of 16 GCI channels defined by G0
and CA 0/2.
D=1: the 6 bit word A, E, S1, S2, S3, S4 is put instead of the six bits received latest during the
timeslot 4n+3 (GCI channel defined by G0 and CA 0/2) and these 6 bit word is transmitted into
any selected output timeslot after switching.
C6 is transmitted first if ANA=1.
C4 is transmitted first if ANA=0.
READ = 1, READ C/I MEMORY.
READ = 0, WRITE C/I MEMORY.
CA 0/2 : These bits define one of eight Command/Indicate Channels.
G0 = 0, DIN4/DOUT4 are selected.
G0 = 1, DIN5/DOUT5 are selected.
D=0: the destination is one of 16 GCI channels defined by G0 and CA 0/2.
D=1:the destination is any TDM (after switching).
