31 / 71 page  DS721A6 31 CS42324 4.2.3 ADC, DAC1, and DAC2 clock selection The ADC, DAC1, and DAC2 can be independently set to use either of the two serial ports as a clock source. Each also has control over which MCLK to use. This allows for full flexibility in configuration of the converter. Master/Slave control is achieved at the serial port level (See Figure 9 on page 29); the internal converters discussed here are always slave. Each converter has a bit in the registers (xxx_SP, where xxx = ADC, DAC1, or DAC2) which allows se- lection of the SCLK/LRCK pair used for the converter. The xxx_MCLK bits select which MCLK source to use for the converter. If the serial port selected for use is in master mode, this selection must be the same as the MCLK_SPx for the serial port which is in use. In Slave mode the MCLK selected must be synchro- nous to the LRCK/SCLK selected by xxx_SP. 4.2.4 High-Impedance Digital Output Each serial port may be placed on a clock/data bus that allows multiple masters, without the need for ex- ternal buffers. The 3ST_SP1, 3ST_SP2 and 3ST_SDOUT bits place the internal buffers for the serial port signals in a high-impedance state, allowing another device to transmit clocks or data without bus conten- tion.
