Function Descriptions
TP8511KB architecture consists core controller some special function registers. special function registers contain 16-bits timers/counters, four general purpose ports, two-sources, two-levels interrupt processor, three direct drive output ports. ports There four general purpose ports TP8511KB, each port 8-bits register store output value. These registers call respectively. addresses registers usage ports same industry standard 80C51 microcontroller. keyboard function descriptions

Completion Code This command sent after successful completion keyboard self test. Echo keyboard sends this code response ECHO command. Keyboards 83AB These bytes sent respond READ command. byte sent first, followed high byte. Keyboard buffer Overrun keyboard buffer overflows, overrun code will replace last byte buffer. code scan code others. Resend When keyboard receives invalid input input with incorrect parity, RESEND command should sent. Keyboard Scan Code Table keyboard contains three scan code sets. system defaults scan code switched `F0' command. following tables show numbers three scan code sets hexadecimal values. scan code ,all keys typematics except pause which make only. When depressed, keyboard will transmit make code that typematic rate long held down. When released, break code sent. more keys held down, only last pressed repeats typematic rate. Typematic operation stops when last pressed released, even other keys being released some other keys still held down. scan code keys individually programmable system command allow keyboard
