11 / 36 page STV0299B 11/36 For the “Unmodulated Tone Burst” Port CTRL 2 is set to 0 and, only one byte, of value 00h is sent. The parity bit is still 1, and as a result, the signal is a continuous train of 12.5 ms. When the modulation is active, the DiSEqC output is driven alternatively to VDD and VSS levels. The DiSEqC and Lock Control, DiSEqC FIFO and DiSEqC Status Registers are in Addresses 08, 09 and 0Ah. Figure 5: Schematic showing Bit Transmission Table 3: Note: 1 Byte to transfer in DiSEqC mode. 2 In mode PortCtrl (1:0)=10, the F22/DiSEqC pin returns to High -2 mode once the transmission is completed. 4.1.13 Standby Mode A low power consumption mode (standby mode) can be implemented (in this mode, fM_CLK = 0). In standby mode, the I2C decoder still operates, but with some restrictions (see Sections 4.1.4 and 4.1.5). Standby mode can be initiated or stopped by I2C bus commands as described in MCR Register 02. At power-on, the circuit starts to operate in standby mode when the STDBY pin (pin 42) is tied to VDD. This guarantees low power consumption for the stand-alone modules (PCMCIA size front-end modules) before any command is initiated. After the power-on sequence, the standby mode is entirely controlled via MCR Register (02).
