OMSU_BYPASS
OCASE_BYPASS
OCASM_BYPASS
The OMSU_BYPASS bit is used to bypass the functionality of the OMSU block. When
OMUS_BYPASS is a logic one, the outgoing memory switch is bypassed and the receive
data bus is passed to the outgoing data bus unmodified. This eliminates the one frame delay
through the OMSU and places the OMSU in a low power mode. When OMSU_BYPASS is a
logic zero, the OMSU is not bypassed and must be configured.
The OCASE_BYPASS bit is used to bypass the functionality of the OCASE block. When
OCASE_BYPASS is a logic one, the transmit CAS extractor is bypassed and the CAS bits are
not extracted from the SBI336 bus. This places the OCASE block in a low power mode.
When OCASE_BYPASS is a logic zero, the OCASE is not bypassed and the CAS bits are
extracted from the SBI336 bus.
The OCASM_BYPASS bit is used to bypass the functionality of the OCASM block. When
OCASM_BYPASS is a logic one, the transmit CAS merge block is bypassed and the CAS
bits are not inserted into the SBI336 bus. This places the OCASM block in a low power
mode. When OCASM_BYPASS is a logic zero, the OCASM is not bypassed and the CAS
bits are inserted into the SBI336 bus.
