ESB radio maximum channel number?

The manuals for the nRF51 and nRF52 list the maximum ESB radio channel number as 100, but in the SDK the guard value in the set channel function is <= 125

(in both the older SDK's using micro_esb.c, and the latest SDK 12.0.0 using nrf_esb.c).

Whch value is correct?

See: SDK 12.0.0 using nrf_esb.c, line 1242 micro_esb.c, line 573 nRF51 Series Reference Manual (page 93) nRF52832 - Product Specification v1.0 (page 216)
