data is read from the SD port data FIFO, SDRDY is

released and SDTKO is pulsed high for 100 nS.

16.3.2 Continuous Mode

To have the CS5376A automatically initiate SD

port transactions whenever data becomes available,

connect SDTKI to a 4 MHz or slower clock source

such as MCLK/2. The first rising edge into SDTKI

after data becomes available in the SD port FIFO

causes the CS5376A to initiate an SD port transac-

tion by driving SDRDY low. If data is not available

in the SD port FIFO, the SDTKI signal is passed

through to the SDTKO output.

Once an SD port transaction is initiated, serial

clocks into SDCLK cause data to be output to

SDDAT, as shown in Figure 35. When all available

data is read from the SD port data FIFO, SDRDY is

released and SDTKO is pulsed high for 100 nS.
