1.2 Important Notes about the Differences between the Module Carriers
In BLE121LR the PIOs P1_0 and P1_1 are reserved for the internal front end control of the module. Also
P1_7 is reserved for this purpose and in case of BLE121LR it can only be used as an output controlling the
external DCDC. Thus in BLE121LR P1_7 is named as DCDC CNTRL.
The important differences between the carriers are shown in the Figure 4 (BLE112 and BLE113 carriers) and
Figure 5 (BLE121LR carrier).
