STLED524

Detailed description

The STLED524 supports the writing of multiple bytes at once. When the first byte is

received, the internal address counter is incremented automatically. Next byte from SPI

frame is written into this new address and so on, until the nth byte is received. If the address

counter reaches the end of address space, it resets to 0 automatically and the writing

continues. When the reading of multiple bytes is performed, the internal address register is

incremented after each byte reading automatically. If the address counter reaches the end

of address space, it resets to 0 automatically and the reading continues.

Protections and interrupts

4.10.1

Registers related to protections and interrupts

There are 3 registers related to protections and interrupts. They are: status, latch and

interrupt enable registers.

OVP_M = 0, the interrupt generated by overvoltage protection is disabled

OVP_M = 1, the interrupt generated by overvoltage protection is enabled

THP_M = 0, the interrupt generated by overtemperature protection is disabled

THP_M = 1, the interrupt generated by overtemperature protection is enabled

OPEN_M = 0, the interrupt generated by open RSET protection is disabled
