Description
s a6402 MegaCore function implementing a universal asynchronous
receiver/transmitter (UART)
s Optimized for FLEX^® and MAX^® architectures
s Uses approximately 162 FLEX logic elements (LEs)
s Programmable word length, stop bits, and parity
s Full duplex operation
s Includes status flags for parity, framing, and overrun errors
s Functionally based on the Harris HD-6402 device, except as noted in
the “Variations & Clarifications” section on page 63
The a6402 MegaCore function implements a universal asynchronous
receiver/transmitter (UART), which provides an interface between a
microprocessor and a serial communications channel. See Figure 1.
