Receive Latch - Motorola MC68838 User Manual

2.2.1 Receive Latch

The receive latch clocks data from the ELM chip. The data signals are latched by using
an internal clock, SAMPLE_CLK (see SYMCLK description in Section 4, Signal
Description). The latched data signals are then relatched by BYTCLK to provide stable
symbols for MAC processing.
