CONTROL PORT SWITCHING CHARACTERISTICS - SPI FORMAT
Inputs: Logic 0 = GND; Logic 1 = VD; C
L
= 20 pF.
Notes: 9.
t
spi
is only needed before first falling edge of CS after power is applied.
t
spi
= 0 at all other times.
10. Data must be held for sufficient time to bridge the transition time of CCLK.
11. For f
cclk
< 1 MHz.
