129 / 175 page  The table below provides a list of the registers for the embedded advanced features page 1. These registers are accessible when PAGE_SEL[3:0] are set to 0001 in PAGE_SEL (02h). Table 338. Register address map - embedded advanced features page 1 Name Type Register address Default Comment Hex Binary FSM_LC_TIMEOUT_L R/W 7A 01111010 00000000 FSM_LC_TIMEOUT_H R/W 7B 01111011 00000000 FSM_PROGRAMS R/W 7C 01111100 00000000 FSM_START_ADD_L R/W 7E 01111110 00000000 FSM_START_ADD_H R/W 7F 01111111 00000000 PEDO_CMD_REG R/W 83 10000011 00000000 PEDO_DEB_STEPS_CONF R/W 84 10000100 00001010 PEDO_SC_DELTAT_L R/W D0 11010000 00000000 PEDO_SC_DELTAT_H R/W D1 11010001 00000000 MLC_MAG_SENSITIVITY_L R/W E8 11101000 00000000 MLC_MAG_SENSITIVITY_H R/W E9 11101001 00111100 Reserved registers must not be changed. Writing to those registers may cause permanent damage to the device. The content of the registers that are loaded at boot should not be changed. They contain the factory calibration values. Their content is automatically restored when the device is powered up. Write procedure example: Example: write value 06h register at address 84h (PEDO_DEB_STEPS_CONF) in page 1 1. Write bit FUNC_CFG_EN = 1 in FUNC_CFG_ACCESS (01h) // Enable access to embedded functions registers 2. Write bit PAGE_WRITE = 1 in PAGE_RW (17h) register // Select write operation mode 3. Write 0001 in PAGE_SEL[3:0] field of register PAGE_SEL (02h) // Select page 1 4. Write 84h in PAGE_ADDR register (08h) // Set address 5. Write 06h in PAGE_DATA register (09h) // Set value to be written 6. Write bit PAGE_WRITE = 0 in PAGE_RW (17h) register // Write operation disabled 7. Write bit FUNC_CFG_EN = 0 in FUNC_CFG_ACCESS (01h) // Disable access to embedded functions registers Read procedure example: Example: read value of register at address 84h (PEDO_DEB_STEPS_CONF) in page 1 1. Write bit FUNC_CFG_EN = 1 in FUNC_CFG_ACCESS (01h) // Enable access to embedded functions registers 2. Write bit PAGE_READ = 1 in PAGE_RW (17h) register // Select read operation mode 3. Write 0001 in PAGE_SEL[3:0] field of register PAGE_SEL (02h) // Select page 1 4. Write 84h in PAGE_ADDR register (08h) // Set address 5. Read value of PAGE_DATA register (09h) // Get register value 6. Write bit PAGE_READ = 0 in PAGE_RW (17h) register // Read operation disabled 7. Write bit FUNC_CFG_EN = 0 in FUNC_CFG_ACCESS (01h) // Disable access to embedded functions registers Note: Steps 1 and 2 of both procedures are intended to be performed at the beginning of the procedure. Steps 6 and 7 of both procedures are intended to be performed at the end of the procedure. If the procedure involves multiple operations, only steps 3, 4 and 5 must be repeated for each operation. If, in particular, the multiple operations involve consecutive registers, only step 5 can be performed. LSM6DSTX Embedded advanced features pages DS14039 - Rev 1 page 129/175 |
