This is revision D of the 16550 family and is the latest design available from National Semiconductor. +Intel 82050 +Essentially a NS16450 squeezed into a 28-pin package with some minor functions +eliminated. Can be strapped for either a 18.432 MHz XTAL (divided by 10 to +produce the BRG clock) or an externally generated 9.216 or 18.432 MHz clock. + +Intel 82510 +A functional expansion of the 82050 with dozens of extra registers. Adds 4-byte +Tx/Rx FIFOs with programmable thresholds, MCS-51 compatible 9-bit protocol, +ASCII/EBCDIC control character recognition, timed interrupts and more. + Known issues: - MESS does currently not handle all these model specific features. |
