52 / 156 page ![]() I²C Interface STV82x7 52/156 Figure 31: Initialization Procedure at Startup (Duration of init phase < 1ms) =0 (bit 0 in DSP_STATUS register) Device Input Configuration Set-up (if needed) INIT_MEM bit ? Hardware Reset Pin LOW Power ON Hardware Reset Pin HIGH Delay > 100 us Clock PLL programmation (Note 1) Load Patch File see Figure 32 =0 (FFh register) Check Patch version =1 HOST_RUN bit = 1 Delay 2 ms Initialization Procedure (bit 0 in DSP_RUN register) (HW_RESET bit = 1 is done by patch file at the end of patch loading) Note 2 NOTE 2: The customer can also set bit HW_RESET = 1 here. (If input configuration has to be changed, it has to be done here) (Start DSP processing) see Figure 33 NOTE 1: Only when the crystal frequency is not 27 MHz. =1 |
