If register 0x85=55h and register 0x8A=AAh, then a hardware reset will be done.

These registers are used to select a setting for gain and threshold for every sensor. There are three available settings. Gain:GA_SIN*[1:0] = 0x0 : Select GA0. 0x1 : Select GA1. 0x2 : Select GA2. 0x3 : Select GA0. Threshold:ON_SIN*[1:0] = 0x0 : Select ON0. 0x1 : Select ON1. 0x2 : Select ON2. 0x3 : Select ON0.

The smaller the value of GA, the higher the gain will be. You can set 3 values for gain. These values are assigned to each sensor by register GA_SIN including CFG_SIN. The settable range: 0x1 ≦ GA ≦ 0xF Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0xC8 GA1[3] GA1[2] GA1[1] GA1[0] GA0[3] GA0[2] GA0[1] GA0[0] 0xC9 - - - - GA2[3] GA2[2] GA2[1] GA2[0] R/W R/W R/W R/W R/W R/W R/W R/W R/W Initial val. 0 0 0 0 0 0 0 0 【0xCA – 0xCC : Value of the threshold for "Off → On"】 Name: ON0、ON1、ON2 Address: 0xCA – 0xCC Description: These registers are used for setting the threshold of the “Off → On” operation. You can set 3 values for threshold. If the 8bit ADC value of each sensor (register SENS_DATA) is larger than this value, then the “Off → On” operation of the sensor is valid. These values are assigned to each sensor by register GA_SIN including ON_SIN. The settable range : 0x00 < OFF < ON < 0xFF Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0xCA ON0[7] ON0[6] ON0[5] ON0[4] ON0[3] ON0[2] ON0[1] ON0[0] 0xCB ON1[7] ON1[6] ON1[5] ON1[4] ON1[3] ON1[2] ON1[1] ON1[0] 0xCC ON2[7] ON2[6] ON2[5] ON2[4] ON2[3] ON2[2] ON2[1] ON2[0] R/W R/W R/W R/W R/W R/W R/W R/W R/W Initial val. 0 0 0 0 0 0 0 0 |
