I-MICROCHIP Core16550 i-Universal Asynchronous Receiver Transmitter
Intshayelelo
I-Core16550 yi-standard Universal Asynchronous Receiver-Transmitter (UART) eqinisekisa ukuhambelana kwesofthiwe kunye nesixhobo esisetyenziswa ngokubanzi se-16550. Ilawula ukuguqulwa kwedatha ye-serial-to-parallel yegalelo kwiimodem okanye ezinye izixhobo ze-serial kwaye yenza ukuguqulwa kwe-parallel-to-serial kwidatha ethunyelwe ukusuka kwi-CPU ukuya kwezi zixhobo.
Ngexesha logqithiso, idatha ibhalwa ngokunxuseneyo kwi-UART's transmit First-In, First-Out (FIFO) buffer. Idatha ke ilandelelaniswe ukwenzela imveliso. Xa ufumana, i-UART iguqula idatha ye-serial engenayo kwi-parallel kwaye yenza kube lula ukufikelela kwiprosesa.
Ukusetyenziswa okuqhelekileyo kwe-16550 UART kubonisiwe kulo mfanekiso ulandelayo.
