Figure
6.48 Mbyte/s parallel buses multiplexed together. The TOH Byte positions are aligned. The SPE Portions may
not be aligned. TPCI/O is the 19.44 MHz input clock. TPDI0 through TPDI7 are the byte wide data inputs
where the LSB is TPDI0. When INVPCK = "0", TPDI (0-7), TSPEI/O, TSYNI/O and TPARI are clocked in on the
Rising Edge of TPCI/O. TPDI(0-7), TSPEI/O, TSYNI/O and TPARI are clocked in on the Falling Edge of TPCI/O
if INVPCK = "1". Input Frame Delineation is controlled by C1J1EN. When set to "0", TSYNI/O and TSPEI/O are
disregarded and the incoming A1/A2 and H1/H2 Bytes are used to determine Frame and SPE alignment. If
C1J1EN = "1" the information content of the A1, A2, H1 and H2 Bytes is disregarded and TSPEI/O and
TSYNI/O are enabled. TSPEI/O is Low during the TOH Byte Times. TSYNI/O is High during the C1 (slot #1
only), J1 and, optionally, V1 Byte times. The V1 Byte time option is enabled when the control H4INT is set to
"1". TMBSEL0 and TMBSEL1 (CR18; 1DC[H], Bits 1 and 2) determine which third of the bus is used.
Serial Datacom
The Rx Terminal Port Serial Datacom Format is shown in Figure 61. The Reference inputs may be either
RRCI/RRFI or RXCK/RXFR. The external reference frame pulse (RRFI) may be from one to eight clock peri-
ods in duration. RTDO is output on the Falling Edge of RTCO. The order of output is MSB
Low during the TOH and, optionally, the POH Byte Times. ENDCMPOH (CR5; 0FD[H], Bit 5) controls the state
of RSPE during the POH Byte times. ENDCMPOH = "0" results in RSPE transitioning Low during these Byte
times. If ENDCMPOH = "1", RSPE remains High during these Byte times. RSYN is High during the C1, J1 and,
optionally, V1 Byte times. The V1 Byte time option is enabled when the control H4INT is set to "1".
