When the CHIP_HARDWARE_RESET bit in the CHIP_MODE register (refer to
section 9.3.2 “CHIP_MODE” on
page 95
) is enabled, all registers can be read from and written to, but do not attempt to access the multicast port vec-
tors in the multicast RAM. The rest of the device is in full reset.
When the CHIP_HARDWARE_RESET bit in the CHIP_MODE register (refer to
section 9.3.2 “CHIP_MODE” on
page 95
) is disabled, but the SW_RESET bit in the CONTROL_REGISTER (refer to
section 9.3.22
“CONTROL_REGISTER” on page 103
) is enabled, the processor has fast access to the multicast RAM. This mode
allows the multicast port vectors to be set up quickly at initialization. In normal device operation, the microprocessor
has a single multicast RAM access every 118 clocks.
