Detailed Description

Macro definitions to manipulate the bits of the status byte.

Status byte explanation :

Bit	Meaning	Comment
7	always 0
6	1 : device is powered
5	1 : device is busy	Wait longer between 2 commands.
4	always 0
3	always 0
2	1 : integrity test failed	Checksum error at power-up.
1	always 0
0	1 : internal math saturation

Macros
#define	ABP2_STATUS_BUSY 0x20
	Sensor is busy.

#define	ABP2_STATUS_MEMERR 0x04
	Memory integrity error.

#define	ABP2_STATUS_MATHSAT 0x01
	Math saturation error.

#define	ABP2_STATUS_MASK (ABP2_STATUS_BUSY \| ABP2_STATUS_MEMERR \| ABP2_STATUS_MATHSAT)
	A bitwise AND of the status byte with this mask will return true in case of error.
