The RT1050 sec ref manual has the following guideline for HW_OCOTP_TIMINGs (section 8.3.3):
tRELAX = tHP_PG = (HW_OCOTP_TIMING[RELAX]+1)/ipg_frequency > 16.2ns
And the RT1060 ref manual has:
tRELAX = tHP_PG = (HW_OCOTP_TIMING[RELAX]+1)/ipg_frequency > 100ns
Which should I observe?
The RT1060's information are right. And the updated RT1050 RM are fixed the information.Please find the detail information as it. https://www.nxp.com/webapp/sps/download/preDownload.jsp?render=true . Thanks for your feedback.
I'm also seeing a discrepancy about how to calculate the condition that the strobe programming timing should meet. The RT1060 ref manual has t_pgm calculated as
t_pgm = [(STROBE_PROG+1) – 2×(RELAX_PROG+1)]/ipg_clk_freq
While the sec ref manual has
t_pgm = [(STROBE_PROG+1) – 2×(RELAX+1)]/ipg_clk_freq
The difference being RELAX_PROG (from TIMING2 register) vs RELAX.
Which is it?
