I refer to "3.7.5 Configurable Serial Peripheral Interface (CSPI) Timing" of the data sheet.
A timing parameter is listed by "Table 43. CSPI Interface Timing Parameters".
IMX25CEC Rev. 10, 07/2013:
- 3.7.5 Configurable Serial Peripheral Interface (CSPI) Timing (P.54)
- Table 43. CSPI Interface Timing Parameters (P.55)
The following is explained in an explanatory note.
What do these parameters mean?
Tsclk = CSPI clock period
Tper = CSPI reference baud rate clock period (PERCLK2)
Tipg = CSPI main clock IPG_CLOCK period
1) Is Tsclk equal to tclko or tclki?
2) What does PERCLK2 mean?
I was not able to find this in a data sheet and a reference manual.
3) Does IPG_CLOCK mean ipg_clk_cspi1-ipg_clk_cspi3?
May I have advice?
