How to write to MAX32630 registers?

I'm aware mbed provides us with a library that handles pretty much everything but I need to access certain registers in order to use the Bluetooth module. Do I need to establish a I2C,SERIAL or SPI communication? A little help please. The register I need to modify is the PWRSEQ_REG0.

The internal registers are included, but buried in the mbed library.

Add these includes:

Include register definitions:

#include "cmsis.h"          // register base address definitions
#include "pwrseq_regs.h"    // power sequence register definitions

Then you can access the registers like this:

Access internal registers:

    uint32_t myPwrseqReg0 = MXC_PWRSEQ->reg0;
    myPwrseqReg0 &= ~(MXC_F_PWRSEQ_REG0_PWR_RTCEN_RUN);
    myPwrseqReg0 |= myRtcEn << MXC_F_PWRSEQ_REG0_PWR_RTCEN_RUN_POS;
    MXC_PWRSEQ->reg0 = myPwrseqReg0;

Thank you! This is exactly what I was looking for.
