SDK 2.7.0 for LPC845BRK: No driver to select low power oscillator for wake up timer?

[1234567890]

In fsl_clock.h of the above SDK usually is a driver function to select a clock source for a peripheral:

with intended parameters of type clock_select_t:

and so on.

But there is no member like kWKT_Clk_From_Lposc or so.

So do I have to select the clock source like PMU->DPDCTRL |= 4; ???

Hi ,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) So do I have to select the clock source like PMU->DPDCTRL |= 4; ?
-- Yes.

Thanks.

Will there be a driver function like

CLOCK_Select(kWKT_Clk_From_Lposc)

be available in near future? I think enabling all clock sources except low power oscillator is not consequent.

Hi ,

Thanks for your suggestion, and I'll report it in the next round of field trial of the SDK library.\
