HT48F06E Hopping Encoder
HT48F06E Hopping Encoder
D/N: HA0121E
Introduction
The Hopping Encoder will encode Address Data, Key Data and Rolling Data (hdata) into a
DES24 encoding format, thus realising a remote control encoding function. Each time the
Key is pressed, the rolling data will increment by 1. This project uses the HT48F50E as
the controlling device.
Functional Description
Code Format
• All Code
Lead Code + idata(24-bit) + hdata(24-bit)
• Lead Code
low part (8.96ms) + high part(4.48ms)
• idata(24-bit)
address data(20-bit) + key status data(4-bit)
• hdata
hdata is rolling data, each time the key is pressed, hdata is incremented by 1。
• idata(24-bit) & hdata(24-bit)
− logic 0
low part (560us) +high part(560us)
− logic 1
low part (560us) +high part (1.68ms)
• Repeat Code
low part (8.96ms) + high part (2.24ms) + low part (560us)
