51 / 68 page ![]() DocID18260 Rev 6 51/68 L99DZ80EP SPI - control and status registers 67 5.3 Control Register 2 7 EC<5> Read/write 0 The reference voltage for the electrochrome voltage controller at pins ECV and ECFD is binary coded. 6 EC<4> Read/write 0 5 EC<3> Read/write 0 4 EC<2> Read/write 0 3 EC<1> Read/write 0 2 EC<0> Read/write 0 1 ECON Read/write 0 The electrochrome control is activated by setting this bit to ‘1’. This enables the driver at pin ECDR and switches OUT10 directly on ignoring bit OUT10_HS on/off. 0 ECFD_LS on/off Read/write 0 The corresponding output driver is activated, if this bit is set. Setting the PWM enable bit, the driver is only switched on, if the PWM timer enables it. Table 34. Control Register 1 (continued) Bit Name Access Reset Content Table 35. Control Register 2 Bit Name Access Reset Content 15 OUT1_OCR Read/write 0 Setting this bit to high enables the overcurrent recovery mode for the corresponding output. 14 OUT2_OCR Read/write 0 13 OUT3_OCR Read/write 0 12 OUT4_OCR Read/write 0 11 OUT5_OCR Read/write 0 10 OUT6_OCR Read/write 0 9 ECV_OCR Read/write 0 8 ECND Read/write 0 Setting this bit to ‘1’ puts the electrochrome controller into the negative discharge mode. 7 OUT1_PWM3 Read/write 0 Setting this bit to ‘1’ enables the PWM mode for the corresponding output. 6 OUT2_PWM1 Read/write 0 5 OUT3_PWM2 Read/write 0 4 OUT4_PWM1 Read/write 0 3 OUT5_PWM2 Read/write 0 2 OUT6_PWM3 Read/write 0 1 ECV_PWM4 Read/write 0 0 ECV_HV Read/write 0 Setting this bit to ‘1’ sets the maximum electrochrome controller voltage to 1.5 V (typ.). A ‘0’ clamps it to 1.2V (typ.). |
