无法让L6480设备进行通信

我目前遇到一个问题，我无法让L6480设备进行通信 - 我认为这可能是由于设备启动故障，但我希望有人可以提供帮助！


我附上了电路图的简化版本，概述了我在设计中所做的电源连接 - 如果我在电源连接上犯了任何错误，请告诉我！主机设备是一个8位Atmel AVR设备（ATmega32A），我正在使用+ 5V逻辑和+ 24V的电机电源。

我测量了电源引脚上的电压：
VS - + 24V
VBOOT - + 24V
VSREG - + 24V
VCC - + 2V5（！？）
VCCREG - + 3V3
VREG - + 3V3
VDD - + 5V

我认为器件仍然处于'上电'状态，因为VCC低于数据表第6.1节中规定的最小值，并且来自OSCOUT引脚的2MHz信号既不是方波也不是正弦波。假设它会是？
我附上了示波器实际信号的图像，显​​示了我得到的波形。

任何反馈将不胜感激!!!

I'm currently experiencing a problem in which I cannot get the L6480 device to communicate - I think this may be due to a device power up fault but I was hoping someone on here could help!


I've attached a simplified version of the circuit diagram, outlining the power connections that I've made in my design - if I've made any mistakes with the power connections then please let me know! The host device is an 8 bit Atmel AVR device (ATmega32A), and I'm working with +5V logic and a motor supply of +24V.

I measured the voltages on the power pins to be:
VS - +24V
VBOOT - +24V
VSREG - +24V
VCC - +2V5 (!?)
VCCREG - +3V3
VREG - +3V3
VDD - +5V

I think the device is still in 'power-up' condition as VCC is below the minimum as stated in section 6.1 of the datasheet, and also the 2MHz signal coming from the OSCOUT pin is neither a square wave or a sine wave which I would have assumed it would be?
I've attached an image of the actual signal from an oscilloscope which shows the waveform that I'm getting.

Any feedback will be greatly appreciated!!!
