TCLK

Serial clock period

100

tCLKL

Low period of serial clock

tCLKH

High period of serial clock

Time between last falling edge of CLK and rising edge of CSn

tCLK / 2

Table 7 SPI Timing Chara cte ristics

Notes:

(1) Synchronization with the internal clock

2 * tCLK_SYS + 10 ns (e.g. at 8 MHz

253 ns)

(2) No synchronization needed because the internal clock is inactive
