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. TPCO is the 6.48 MHz output clock, which may be continuous or
may be gapped. TPDO0 through TPDO7 are the byte wide data outputs where the LSB of the byte is output on
TPDO0. RSPE is Low during the TOH and, optionally, POH 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". Two controls
regulate TPCO gapping. They are DISPCKG (CR5; 0FD[H], Bit 4) and ENDCMPOH. DISPCKG is only effec-
tive in this mode. When DISPCKG is set to "1" TPCO will be continuous. A setting of "0" will introduce gaps in
TPCO during the TOH Byte Times. ENDCMPOH controls the gapping of the POH Bytes when DISPCKG = "0".
If ENDCMPOH = "0", TPCO is also gapped during the POH Byte times. When ENDCMPOH = "1", there will be
no gaps in TPCO during these Byte times if DISPCKG = "0". ENDCMPOH also controls the state of RSPE dur-
ing these Byte times. This function is independent of the setting of DISPCKG. ENDCMPOH = "0" results in
RSPE transitioning Low during the POH Byte times. If ENDCMPOH = "1", RSPE remains High during these
Byte times. The polarity of TPCO can be inverted with the control INVPCK. A value of "0" results in TPDO(0-7),
RSPE, RSYN and TPARO being output on the Falling Edge. When INVPCK = "1", these signals are instead
output on the Rising Edge of TPCO.
