When the processor is running off the 32 kHz clock, the short chip select option will pro-
duce chip select signal that is the width of a single 32 kHz clock (30.5 microseconds); oth-
erwise the timing is identical to the short chip select options based off the main oscillator.
Read strobe figures are shown below.
