# CP_IsDivBusy

## C Specification

  `#include <nitro/cp.h>`
  `s32 CP_IsDivBusy( void );`

## Arguments

None.

## Return Values

Whether the divider is busy or not. 0 means ready state and non-0 means busy state.

## Description

Determines whether the divider is busy or not. After writing to a divider register, it will be in busy status for a fixed cycle period. To get the result of division, you need to read when it is no longer busy. The calculation cycle is as follows. (The calculation cycle is a cycle number based on 33.514 MHz. The CPU cycle conversion is a cycle number based on 67.028 MHz.))

Division Mode | Calculation | Calculation Cycles | CPU Cycle Conversion
CP_DIV_32_32BIT_MODE | 32-bit divided by 32-bit | 18 cycles | 36 cycles
CP_DIV_64_32BIT_MODE | 64-bit divided by 32-bit | 34 cycles | 68 cycles
CP_DIV_64_64BIT_MODE | 64-bit divided by 64-bit | 34 cycles | 68 cycles

## Internal Operation

`Reference DIVCNT(0x4000280) of the IO register.
`
