OW/APS Mode
The Rx E
output data (ORDO) consists of the E1 Byte, four Null Bytes, the K1 Byte, the K2 Byte, one Null Byte and the
E2 Byte. The order of output is MSB
respectively. The position of these two signals is determined by ALTOW (CR2; 0FA[H], Bit 3). When set to a "0"
value, SRFR occurs one clock period before the MSB of E1 and LRFR occurs one clock period before the MSB
of E2. A Setting of "1" results in SRFR and LRFR occurring coincident with the MSB of the E1 and E2 Bytes,
respectively. The signal RAP is an active Low pulse that occurs one clock time after the LSB of the K2 Byte.

OTCO. The input data (OTDI) is clocked in and TAP is clocked out on the Falling Edge. OTDI consists of the E1
Byte, one Null Byte, the K1 and K2 Bytes, three Null Bytes, the E2 Byte and a Null Byte. The order of input is
MSB
signals is determined by ALTOW. When ALTOW is "0", STFR occurs 1½ clock periods before the MSB of E1 is
sampled and LTFR occurs 1½ clock periods before the MSB of E2 is sampled. A Setting of "1" for ALTOW
results in STFR and LTFR occurring one half clock cycle before the MSB of the E1 and E2 Bytes, respectively,
is sampled. The signal TAP is an active Low pulse that occurs one clock time before the MSB of the K1 Byte is
sampled.
