Reading Eeprom With Sici - Infineon TLE5014P16 User Manual

TLE5014
GMR-Based Angle Sensor
Examples
Table 21 Reading of angle value (AVAL register, 0x02) (cont'd)
Type Command
sensor stays in this mode with SICI interface enabled. To return to normal interface, sensor reset is necessary
(can be done by power-down or sending the reset command 0x0001 to address 0x01:
write 0x4011

Reading EEPROM with SICI

The following example in
0x006. In this example, it is assumed, that the sensor is connected in a bus mode configuration and has the
ID = 1. First the EEPROM page 0x006 is mapped to registers 0x60 to 0x67. Then these registers are read.
Further details for bus mode programming can be found in
Table 22 Reading of EEPROM page 0x006)
Type Command
write 0x0771
write 0x06C1
wait until power-on of sensor is finished
write 0x47A1
write 0x06C1
write 0x4681
read 0xC601
read 0x8611
read 0x8621
read 0xC631
read 0x8641
read 0xC651

Comment
Write command to address 0x77
unlocks registers
Write command to address 0x6C with DATA 0x4000
sensor will stay with SICI interface after power-on time
and not switch to preconfigured interface
SENT/SPC/PWM;
The first two commands have to be sent within the start-
up time of the sensor.
Write ID-WORD for ID=1 to address 0x7A;
only sensor with ID=1 is addressed; only necessary in
case of programming in a bus mode configuration
Write command to address 0x6C with DATA 0xC000
internal DSP is stopped
Maps EEPROM page 0x006 to registers 0x60 ... 0x67
(WRITE command to address 0x68)
Reads DATA from register 0x60,
corresponds to content of EEPROM address 0x0060
Reads DATA from register 0x61,
corresponds to content of EEPROM address 0x0062
Reads DATA from register 0x62,
corresponds to content of EEPROM address 0x0064
Reads DATA from register 0x63,
corresponds to content of EEPROM address 0x0066
Reads DATA from register 0x64,
corresponds to content of EEPROM address 0x0068
Reads DATA from register 0x65,
corresponds to content of EEPROM address 0x006A
Reads DATA from register 0x66,
corresponds to content of EEPROM address 0x006C
