either RRCI/RRFI, RXCK/RXFR, or RRCI/RRFI. The external reference frame pulses (RRFI or RRFI) may be
from one to eight clock periods in duration. TPDO0 through TPDO7 are the byte wide data outputs where the
LSB is TPDO0. RSPE is Low during the TOH 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". The polarity of TPCO can
be inverted with the control INVPCK (CR5; 0FD[H], Bit 3). A value of "0" results in TPDO(0-7), RSPE, RSYN
and TPARO being output on the Falling Edge. When INVPCK = "1", the information is output on the Rising
Edge of TPCO.

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, J1 and, optionally, V1 Byte times. The V1 Byte time option is
enabled when the control H4INT is set to "1".
