Register Descriptions
DE Registers
Table 114. Registers 0x1010—0x1015: Sequencer Provisioning Registers (R/W) (continued)
Reset default of register 0x1010 = 0x0002.
Reset default of register 0x1011 = 0x2210.
Reset default of registers 0x1012, 0x1014 = 0x0435.
Reset default of registers 0x1013, 0x1015 = 0x0025.
Note: The settings of these registers must be consistent with core mode register (address 0x0010).

Sequencer Control. Selects STS-3/STM-1, STS-
12/STM-4, or STS-48/STM-16 mode for the data
engine. Allowed values are as follows:
STS-3/STM-1 = 0x0001
STS-12/STM-4 = 0x0003
STS-48/STM-16 = 0x0002
Reserved. These bits must be written to their reset
default value (00000000000000).
Sequencer Rate. Configures internal clock
derived from TxCKP/TxCKN.
0 = STS-3/STM-1 (internal clock = 19.440 MHz)
1 = STS-12/STM-4 or STS-48/STM-16
(internal clock = 77.760 MHz)
Sequencer Mode. Used with bit 1 above to select
the mode.
0 = STS-48/STM-16
1 = STS-3/STM-1 or STS-12/STM-4
Initial Counts. This register must be set to the
default value (0x2210).
OHP Marker Low. This register must be
programmed as follows:
STS-48/STM-16 = 0x0435
STS-12/STM-4 = 0x0435
STS-3/STM-1 = 0x010B
OHP Marker High. This register must be
programmed as follows:
STS-48/STM-16 = 0x0025
STS-12/STM-4 = 0x0025
STS-3/STM-1 = 0x0007
Sequence Provisioning for OHP Marker Low.
This register must be programmed as follows:
STS-48/STM-16 = 0x0435
STS-12/STM-4 = 0x0435
STS-3/STM-1 = 0x010B
Sequence Provisioning for OHP Marker High.
This register must be programmed as follows:
STS-48/STM-16 = 0x0025
STS-12/STM-4 = 0x0025
STS-3/STM-1 = 0x0007
