bits
t1: The time from setting VCCSEL bits until VCCOK = 1.
tto: The time from setting VCCSEL bits until VCCTMR times out. At t1 (if RDYST = 1) or tto (if RDYST = 0),
activation starts. It is suggested to have RDYST = 0 and use the VCCTMR interrupt to let MPU know when
sequence is starting.
t2: time from start of activation (no external indication) until IO goes into reception mode (= 1). This is approximately
4 SCCLK (or SCECLK) clock cycles.
t3: minimum one half of ETU period.
t4: ETU period.
Note that in Sync mode, IO as input is sampled on the rising edge of CLK. IO changes on the falling edge of CLK,
either from the card or from the 73S1210F. The RST signal to the card is directly controlled by the RSTCRD bit
(non-inverted) via the MPU and is shown as an example of a possible RST pattern.
