Parameters

delay

Delay in seconds

#define delay_us

(

delay

)

((delay) ? cpu_delay_us(delay) : cpu_delay_us(1))

Delay in at least specified number of microseconds.

Parameters

delay

Delay in microseconds

void delay_init

(

void

)

Initialize the delay driver.

Not used in cycle mode.

This must be called during start up to initialize the delay routine with the current used main clock. It must run any time the main CPU clock is changed.
