Freescale Semiconductor
Note:
1. 0.95 V < V
2. Periodically sampled, not 100% tested
3. All times assume noise free inputs.
4. All times assume internal clock frequency of 200 MHz.
5. SHI_1 specs match those of SHI
6. Slave timings should equal the serial clock high period + the serial clock low period.
No.
