The ISP1109 is in transparent UART mode, if bit UART_EN of the Mode Control 1 register
is set.
In transparent audio mode, the ISP1109 will disable its DP and DM driver. The carkit
interrupt detector is enabled. The built-in analog switches will be tuned based on the
selection of carkit audio mode:
The ISP1109 is in transparent audio mode, if bit UART_EN of the Mode Control 1 register
is cleared, and bit AUDIO_EN of the Audio Control register is set.
In transparent general-purpose buffer mode, the DAT/VP and SE0/VM pins are connected
to the DP and DM pins, respectively. Using bits TRANSP_BDIR1 and TRANSP_BDIR0 of
the Mode Control 2 register as specified in
transfer. The ISP1109 is in transparent general-purpose buffer mode if bit UART_EN = 0,
bit AUDIO_EN = 0, and bit TRANSP_EN = 1.

If UART_PIN_SEL = 1:
– For the TxD signal: From SE0/VM (V
– For the RxD signal: From DP (REG3V3 level) to DAT/VP (REG3V3 level).
Stereo mode: SPKR_L on DM and SPKR_R on DP
Mono and MIC mode: SPKR_L on DM and MIC on DP.
