Manual Verification
In Phoenix, put phone in Local Mode; next, BB Self Tests - select ST_UEM_CBUS_IF_TEST,
then Run.
Troubleshooting
Connections tested at UPP: CBUSDA (pad G2) check test point J407, CBUSCLK (padG1)
check test point J406, CBUSENX (pad F3) check test point J408. At UEM: CBUSDA (pad
B7), CBUSCLK (pad A8), and CBUSENX (pad C8). Bus interface name is AUDUEMCTRL
(3:0).

Test 7 ST Aux DA

Description
The purpose of this test is to verify the AUXD and UEMINT data connections between the
UPP and the UEM are intact. MCU will set the UEM looptest mode by programming the
Loop Test bit in the CBUS General Control 2 register. Next, DSP will write a word to AuxD
register, thus causing a rising edge on the AuxD line. MCU will verify that UEMInt occurs.
Explanation of Result
Pass or Fail
Manual Verification
In Phoenix, put phone in Local Mode; next BB Self Tests - select
ST_AUX_DA_LOOP_TEST; then Run.
Troubleshooting
Connections tested: 1) UPP: AUXDA (pad L2) via bus interface RFCONVDA(5) to UEM:
AUXDA (pad D11). 2) UPP: UEMINT (pad J2) check test point J405, via bus interface
AUDUEMCTRL(0) to UEM; UEMINT (pad A10).

Test 8 ST EAR Data

Description
The purpose of this test is to verify the EAR and MIC data connections between the UPP
and the UEM are intact. MCU will set the UEM looptest mode by programming the Loop
Test bit in the CBUS General Control 2 register. Next, DSP will write an arbitrary pattern
to CodexRx register and then read the data from the Codec Tx register.
