The IMSU_BYPASS bit is used to bypass the functionality of the IMSU block. When
IMSU_BYPASS is a logic one, the incoming memory switch is bypassed and the incoming
data bus is passed to the transmit data bus unmodified. This eliminates the one frame delay
through the IMSU and places the IMSU in a low power mode. When IMSU_BYPASS is a
logic zero, the IMSU is not bypassed and must be configured.
The ICASE_BYPASS bit is used to bypass the functionality of the ICASE block. When
ICASE_BYPASS is a logic one, the incoming CAS extractor is bypassed and the CAS bits
are not extracted from the SBI336 bus. This places the ICASE block in a low power mode.
When ICASE_BYPASS is a logic zero, the ICASE is not bypassed and the CAS bits are
extracted from the SBI336 bus.
The ICASM_BYPASS bit is used to bypass the functionality of the ICASM block. When
ICASM_BYPASS is a logic one, the incoming CAS merge block is bypassed and the CAS
bits are not inserted into the SBI336 bus. This places the ICASM block in a low power
mode. When ICASM_BYPASS is a logic zero, the ICASM is not bypassed and the CAS bits
are inserted into the SBI336 bus.
