Function
OCIF_PAR
(A) RPU_PAR
(A) Parity over data bus (programmable to odd or even)
(B) TLU_PAR
(B) Parity over data bus (programmable to odd or even)
(C) RPP_PAR
(C) Parity over data bus (programmable to odd or even)
The receive parity (RPP_PAR) signal indicates the parity
calculated over the RPP_DAT bus. RPP_PAR is valid whenever
RPP_VAL or RPP_SX are asserted.
(D) TLP_PAR
Output
(D) Parity over data bus (programmable to odd or even)
The transmit parity (TLP_PAR) signal indicates the parity
calculated over the TLP_DAT bus. TLP_PAR is considered valid
only when TLP_ENB or TLP_SX is asserted.
OCIF_SOC_SOP
(A) RPU_SOC
(A) Start of cell. Active high signal asserted to indicate the start of
cell position. It is expected that, in case of loss of
synchronization, that RPU_SOC will serve to resynchronize the
interface.
(B) TLU_SOC
(B) Start of cell. Active high signal asserted to indicate the start of
cell position. It is expected that, in case of loss of
synchronization, that TLU_SOC will serve to resynchronize the
interface.
(C) RPP_SOP
(C) Start of packet. RPP_SOP is used to delineate the packet
boundaries on the RPP_DAT bus. When RPP_SOP is high, the
start of the packet is present on the RPP_DAT bus.
RPP_SOP is required to be present at the start of every packet
and is considered valid when RPP_VAL is asserted..
(D) TLP_SOP
Output
(D) Start of packet. TLP_SOP is used to delineate the packet
boundaries on the TLP_DAT bus. When TLP_SOP is high, the
start of the packet is present on the TLP_DAT bus.
TLP_SOP is required to be present at the beginning of every
packet and is considered valid only when TLP_ENB is asserted.
