Though controlling the module states manually, you can test the performance and
parameter in each state by using the CMU200 or other matching software.
2. Testing the key signals
On the debugging board, the test points of all signification signals are led out for
testing. Figure 5-13 shows positions of the test points.
Figure 5-13 Test point position
The test points shown in the previously figure are described as follows:
TS408: WAKE_NB_N (signal that the module uses to activate the PC)
TS406: WAKEUP_N (signal that the PC uses to wake up the module)
TS407:W_DISABLE_N (signal for disabling the RF function of the module)
TS409: PERST_N (module reset signal)
TS201: MIC_P (input signal of microphone +)
TS202: MIC_N (input signal of microphone –)
TS203: EAR_P (input signal of earphone +)
TS204: EAR_N (input signal of earphone –)
TS205: UART1_RX (Rx signal of the serial port 1)
TS206: UART1_TX (Tx signal of the serial port 1)
TS207: UART1_RI (RI signal of the serial port 1)
TS209: UART1_CTS (CTS signal of the serial port 1)
TS210: UART1_RFR (RFR signal of the serial port 1)
TS211: UART1_DTR (DTR signal of the serial port 1)
