I’m trying to configure GTM module of TC274D microcontroller on my evaluation board TriBoard TC274 V1.0.
GTM module version is 1.4.2.

I have the next problems:
1. When I try to access registers GTM_TIM0_CH0_IRQ_MODE, GTM_TIM0_IN_SRC and some others, I get Bus Error trap.
2. When I write any value to GTM_TIM0_CH0_CTRL register, only TIM_EN bit is set and others are ignored and set as 0.
3. Bit AEI_USP_ADDR of GTM_IRQ_NOTIFY register is set after GTM enabling and can’t be cleared by writing 1 to it.

Could you please to help me with my issues?

You will have to clear the endinit bit in the CPU watchdog to gain access to the registers. Read about endinit protection in the user manual.
