how to determine chip revision for nrf52832 from FICR.INFO.VARIANT

[Allen]

Hello,

The following defines can be found in nrf52_bitfields.h. Are all these register values used for REV 1 chips? In otherwise, the last digit isn't significant? If so, what does the last digit represent?

#define FICR_INFO_VARIANT_VARIANT_AAB0 (0x41414230UL) /*!< AAB0 */

#define FICR_INFO_VARIANT_VARIANT_AABA (0x41414241UL) /*!< AABA */

#define FICR_INFO_VARIANT_VARIANT_AABB (0x41414242UL) /*!< AABB */

Thanks

Hi Allen, 

Please see SoC revisions and variants and the INFO.VARIANT register.

AAB0 is then revision 1 and AAE0 is revision 2. 

AABA and AABB are the Engineering versions.
