Register Descriptions
OHP Registers
This section gives a brief description of each register bit and its functionality. All algorithms are described in the
main text of the document. The abbreviations after each register indicate if the register is read only (RO), read/
write (R/W), write only (WO), or clear-on-read or clear-on-write (COR/W).
0x indicates a hexadecimal value in the Reset Default column. Otherwise, the entry is binary. This is true for every
register table in the document.
Table 70. Register 0x0400: OHP Macrocell Version Number (RO)
Reset default of register = 0x0000.
Table 71. Register 0x0401: OHP Interrupt (RO)
Reset default of register = 0x0000.
Table 72. Registers 0x0402—0x0409: Delta/Event (COR/W)
Reset default of registers = 0x0000.

OHP Macrocell Version Number. The version
of the macrocell will increment each time a
change occurs to the macrocell functionality.
Reserved. These bits must be written to their
reset default value (0x000).
OHP Interrupt. Active-high interrupt bits for
channels D to A. Each bit is the ORing of all
event and delta bits of that channel. In STS-48/
STM-16 mode, INT[A] is valid.
Line/Multiplex RDI Delta. Delta bits indicate a
change of state for the line/multiplex RDI state
bits (LRDIMON[A—D]). Their mask bits are
LRDIMONM[A—D]. Only LRDIMOND[A] is
valid for STS-48/STM-16.
Line/Multiplex AIS Delta. Delta bits indicate a
change of state for the line/multiplex AIS state
bits (LAISMON[A—D]). Their mask bits are
LAISMONM[A—D]. Only LAISMOND[A] is valid
for STS-48/STM-16.
APS Babble Event. Each bit is active-high to
indicate the inconsistence in K1 byte of that
channel. Their mask bits are
RAPSBABLEM[A—D]. Only RAPSBABLEE[A]
is valid for STS-48/STM-16.
