11 / 58 page  2003 Microchip Technology Inc. Preliminary DS21790A-page 11 MCP2140 2.5 Encoder/Decoder The encoder converts the UART format data into the IrDA Standard format data and the decoder converts IrDA Standard format data into UART format data. 2.5.1 ENCODER (MODULATION) The data that the MCP2140 UART received (on the TX pin) that needs to be transmitted (on the TXIR pin) will need to be modulated. This modulated signal drives the IR transceiver module. Figure 2-5 shows the encoding of the modulated signal. Each bit time is comprised of 16-bit clocks. If the value to be transmitted (as determined by the TX pin) is a logic-low, the TXIR pin will output a low level for 7-bit clock cycles, a logic high level for 3-bit clock cycles or a minimum of 1.6 µsec (see Parameter IR121). The remaining 6-bit clock cycles will be low. If the value to transmit is a logic-high, the TXIR pin will output a low level for the entire 16-bit clock cycles. FIGURE 2-5: ENCODING Note: The signal on the TXIR pin does not actu- ally line up in time with the bit value that was transmitted on the TX pin, as shown in Figure 2-5. The TX bit value is shown to represent the value to be transmitted on the TXIR pin. BITCLK TX Bit TXIR 01 0 0 0 1 16 CLK 7 CLK Start Bit Data bit 0 Data bit 1 Data bit 2 Data bit ... 24 Tosc Value |
