Description
asynchronous mode: when PWDN bit is set to logic 1, the
CLKPD[1] and CLKPD[2] bits define the card clock
synchronous mode: when the PWDN bit and the START bit are
set to logic 1, the CLKPD[2] bit remains logic 0 and the clock
frequency is controlled by the CLKPD[1] bit
asynchronous mode: the card clock =

asynchronous mode: when the PWDN bit is set to logic 0 the
CLKDIV[1:0] bits define the card clock frequency.
synchronous mode: the CLKDIV[1:0] bits are logic 0
asynchronous mode: the card clock is stopped and set to
logic 0
synchronous mode: the card clock is set to logic 0
