Indirect Register Definitions
To write to the TVP5154A indirect registers, it is required that the registers be unlocked using a password.
The password prevents undesirable writes into the device at start-up due to power surges, for example.
The following example demonstrates the method for unlocking the indirect registers.
After writing to the desired indirect registers described in the following text, it is recommended that the
device be locked again.
Unlock the device
1. Write 0x51 to I2C_0x21. //MSB data
2. Write 0x54 to I2C_0x22. //LSB data
3. Write 0xFF to I2C_0x23. //Data address
4. Write 0x04 to I2C_0x24. //Write command
Lock the device
1. Write 0x00 to I2C_0x21. //MSB data
2. Write 0x00 to I2C_0x22. //LSB data
3. Write 0xFF to I2C_0x23. //Data address
4. Write 0x04 to I2C_0x24. //Write command
Indirect registers are written to by performing the following I2C transaction:
START : DEVICE_ID_w : 0x21 : DATA_HIGH : STOP
START : DEVICE_ID_w : 0x22 : DATA_LOW : STOP
START : DEVICE_ID_w : 0x23 : ADDRESS_LOW : STOP
START : DEVICE_ID_w : 0x24 : WR_STROBE : STOP
To read from an indirect register, the following I2C transaction should be performed:
START : DEVICE_ID_w : 0x23 : ADDRESS_LOW : STOP
START : DEVICE_ID_w : 0x24 : RD_STROBE : STOP
START : DEVICE_ID_r : 0x21 : data_msb : STOP
START : DEVICE_ID_r : 0x22 : data_lsb : STOP
Where:
DEVICE_ID_w is the selected TVP5154A device ID with the read/write bit (LSB) set to write.
DEVICE_ID_r is the selected TVP5154A device ID with the read/write bit (LSB) set to read.
ADDRESS_LOW is the low byte of the register address.
WR_STROBE is 0x06.
RD_STROBE is 0x05.
Note, the upper byte of the address is not directly used but is replaced by the corresponding STROBE
signal.
Each indirect register is 16 bits wide.
