main mode.
35 C_SDO/I2S_TX DO As an I2S interface: can work in master/slave
mode formula. If working in master mode, read
from the vocoder Take PCM serial data to
HR_C6000; if Working in slave mode, the
vocoder will write PCM data Go to HR_C6000.
As an SPI interface: HR_C6000 will Output voice
data from CodecADC to vocoding SPI port.
36 C_SCLK/I2S_CK DO/DI As an I2S interface: can work in master/slave
mode formula. If working in master mode, if
working in Main mode, the I2S master that is
provided to the vocoder Clock; if working in slave
mode, for vocoder When working with the I2S
interface of the HR_C6000 bell As an SPI
interface: a slice of the vocoder SPI port selected.
37 C_CS/I2S_FS DO/DI As an I2S interface: can work in master/slave
mode formula. If working in master mode,
provide vocoding Read and write I2S left and
right channel data enable; Fruit work is provided
from the mode, the vocoder HR_C6000 reads and
writes the left and right channels of serial data
Enable.
38 TEST_MODE DI Test mode configuration pin, 1 is test mode, 0 for
normal working mode.
39 RESETn DI System reset signal, active low.
40 VSS33 P Digital IO 3.3V power supply.
41 V_SDI DI Universal vocoder SPI port serial data input.
42 V_SDO DO Universal vocoder SPI port serial data output.
43 V_SCLK DI Universal vocoder SPI port serial clock.
44 V_CS DI Universal vocoder SPI port chip select
45 DBIST_IN DI NC. Connect to ground.
46 DBIST_OUT DO NC
47 PWD DI Chip PowerDown control pin, high level activates
the PowerDown state.
48 TIME_SLOT_INTER DO 30ms time slot interrupt.
49 SYS_INTER DO System control is interrupted.
50 DO The radio end sends related parameters to
configure interrupts, such as sending the mixer
frequency configuration.
51 DO The radio end receives the relevant parameter
configuration interrupt, such as receive the mixer
frequency configuration.
52 VSS12 G The kernel is digitally ground.
53 VDD12 P Core digital 1.2V power supply.
