All rights reserved. www.rohm.com TSZ22111・15・001 14.Jul.2016 Rev.004 【 0xC0 – 0xC7 : Select a setting for Gain and Threshold for “Off→On”】 Name: CFG_SIN Address: 0xC0 – 0xC7 Description: You can set 3 values for gain and set 3 values for threshold for “Off → On” to this IC. These registers are used to select a setting for gain and threshold from three settings for every each sensor. 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 gain will be higher. You can set 3 values for gain. These value are assigned to each sensor by register GA_SIN included 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 for setting the threshold for “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, the valid “Off → On” operation of the sensor is. These value are assigned to each sensor by register ON_SIN included CFG_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 Initial val. - 0 0 0 0 0 0 0 【 0xCD : Value of the threshold for "On → Off"】 Name: OFF Address: 0xCD Description: This register is for setting the threshold for “On → Off” operation. If the 8bit ADC value of each sensor (register SENS_DATA) is smaller than this value, the valid “On → Off” operation of the sensor is. The setting range : 0x00 < OFF < ON < 0xFF Bit7 Bit6 Bit5 Bit4 Bit3 Bit2 Bit1 Bit0 0xCD - OFF [6] OFF [5] OFF [4] OFF [3] OFF [2] OFF [1] OFF [0] 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 |
