how to keep a delay for write in to accelerometer

Question

Hi, 
 i am using accelerometer sensor, which is i2c compatible. 
 i have nrf51822 pca10001 board. 
 in accelerometer datasheet it is mention as after every write there should be delay of 450 us. 
 so i kept delay as 
 void delay()
{
uint32_t i=0;
for(i=0;i<0xffffffff;i++);
} 
 but it is taking too much time. 
 so i want know , what should should be i value for nearly 460 us delay. 
 means how many clock cycle it wil take. 
 i don't want to use timer in this case. 
 kindly suggest me

You can use the nrf_delay.h library for small delays.
For larger delays, I would recommend using a timer instead (for best current consumption)
