TLC5916-Q1 LED Driver Serial interface
My question is can I assign it ( OPTION 1 ) to I/O pins


Yes. The TLC5916 is not an SPI bus device. It is very similar, and most (ab)use hardware SPI to use it, but it is a simple shift register interface. Using GPIO to bitbang is how it would be used.


  or ( OPTION 2 ) to I2C pins.


No, the TCL5916 does not use I2C. TI has similar devices with I2C as seen here. The TLC59108 is an I2C version with near equal specs.
