Description
Clock Stop (CST). In the case of an asynchronous card,
bit CST defines whether the clock to the card is stopped or not; if
bit CST is reset, then the clock is determined by bits AC0, AC1
and AC2.
Synchronous Clock (SC). In the event of a synchronous card,
then contact CLK is the copy of the value of bit SC; in reception
mode, the data from the card is available to bit UR0 after a read
operation of register URR; in transmission mode, the data is
written on the I/O line of the card when register UTR has been
written to and remains unchanged when another card is
selected.
Alternating Clock (AC). All frequency changes are
synchronous, thus ensuring that no spikes or unwanted pulse
widths occur during changes.
