12.1 Test Session

The PN7150 has the ability to generate a continuous PRBS pattern on the RF interface.
Whatever the test command used by the DH, it is necessary to implement a "test session",
which isolates the test mode from a regular "NCI session" of PN7150. This test session is
defined thanks to the following sequence:
• Reset/Initialize the PN7150 using CORE_RESET_CMD/CORE_INIT_CMD
• Launch selected test function
• Get the response transporting executed test status
• Reset/ Initialize the PN7150 using CORE_RESET_CMD/CORE_INIT_CMD (except
