how to sent 5 different data in 5 five clock cycles

Hello everyone

I need to sent 5 different 16 bits data in 5 five clock cycles to my costum component.
My Altera board is driven by a 50MHz oscillator (a period of 0.02 µs).

so should I write

IOWR_16DIRECT(BASE , OFFSET, DATA_1);
usleep(0.02);
IOWR_16DIRECT(BASE , OFFSET, DATA_2);
usleep(0.02);
.
.
.
IOWR_16DIRECT(BASE , OFFSET, DATA_5);
