i.MXRT1176 OCOTP clock source

Hi,

I am trying to figure out which root clock is supplying the OCOTP peripheral of MIMXRT1176 controller. According to reference manual page 1499 Table 15-5 the clk_enable_ocotp controls LPCG37. However there is no mentioning about LPCG37 in any root clock related chapter/table.

I need this information to calculate the source clock in order to initialize the OCOTP peripheral via OCOTP_Init(OCOTP_Type *base, uint32_t srcClock_Hz).

best regards

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
The OCOTP doesn't have the timing control register or similar option to configure.
So it needn't configure the clock source to drive it and MCU itself is in charge of it.
Hope this is clear.
Have a great day,
TIC
