5 / 20 page  Bit Coding Formats The NM95HS0102 HiSeC Generator supports eleven-bit coding formats which may be used for IR and RF transmis- sion Seven-bit formats are available for RF applications and four are available for IR applications One-bit format is reserved for future use Bit coding formats are selected by configuring four bits in the EEPROM array IRSEL PRSEL2 PRSEL1 and PRSEL0 Table II shows the possible bit coding options available Each bit coding format has a distinction which may be ad- vantageous for a particular application RF bit coding format 0 is the simplest bit coding scheme and data may be easily recovered from a transmission by exclusive OR-ing the data and clock stream Both RF bit coding formats 0 and 2 have a DC level that is independent of the data RF format 4 and the IR modes operate with a constant transmission energy per message and RF coding formats 1 3 5 and 7 are pulse-width modulated (PWM) formats which are relatively easy to decode RF coding format 7 has a low duty cycle The IR bit coding formats are modulated versions of RF coding format 4 and are all suitable for IR applications The duty cycle and number of pulses are variable among these four to allow the user to fine tune the IR circuit power curve IR bit coding formats all follow the same general pattern In this mode a logic ‘‘1’’ is always two periods long and a ‘‘0’’ is always three periods long This may be an important con- sideration when considering preamble and sync timing Waveform diagrams for all available RF and IR bit transmis- sion coding formats are shown below TABLE II Transmission Bit Coding Options IRSEL PRSEL2 PRSEL1 PRSEL0 Function 0 0 0 0 RF Bit Coding Format 0 0 0 0 1 RF Bit Coding Format 1 0 0 1 0 RF Bit Coding Format 2 0 0 1 1 RF Bit Coding Format 3 0 1 0 0 RF Bit Coding Format 4 0 1 0 1 RF Bit Coding Format 5 0 1 1 0 Reserved 0 1 1 1 RF Bit Coding Format 7 1 0 0 0 IR Bit Coding Format 1 1 0 0 1 IR Bit Coding Format 2 1 0 1 0 IR Bit Coding Format 3 1 0 1 1 IR Bit Coding Format 4 1 1 X X Reserved Bit Transmission Coding Formats RF Bit Coding Format 0 (Manchester Code) TLD12302 – 6 RF Bit Coding Format 1 (33%66% End High) TLD12302 – 7 RF Bit Coding Format 2 (50% Duty Cycle) TLD12302 – 8 RF Bit Coding Format 3 (25%50% Start High) TLD12302 – 9 RF Bit Coding Format 4 (IR Style) TLD12302 – 10 RF Bit Coding Format 5 (33%66% Start High) TLD12302 – 11 http www nationalcom 5 |
