... PT6311 KEY MATRIX & KEY INPUT DATA STORAGE RAM PT6311 Key Matrix consists arrays as shown below Each data inputted by each key are stored as follows. They are read by a READ Command, starting from the last significant bit. When the most significant bit of the data (SG12, b7) has been read, the least significant bit of the next data (SG1, b0) is read. K1… ...

... LED DISPLAY PT6311 provides 5 LED Display Terminals, namely LED1 to LED5. Data is written to the LED Port starting from the least significant bit (b0) of the port using a WRITE Command. Each bit starting from the least significant (b0) activates a specific LED Display Terminal -- b0 corresponds LED1 Display, b1 activates LED2 and so forth. Since there are only 5 LED display terminals, bits (b5 ~ b7) are not used and therefore ignored ...
