The pull-up resistor size is dependent on the bus capacitive load (this includes all device leakage currents). The maximum bus capacitive load for each I2C bus is 400 pF. The pull-up resistor cannot be made so large that the bus time constant (Resistance X Capacitance) does not meet the...
PEP 必须使用 ParentName.Buffer 中的地址指向的已分配内存来提供父名称。由于此内存是预先分配的,因此无法更改其大小。 如有必要,PEP 负责截断父名称,使其不超过 ParentName.MaximumLength (包括终止 UNICODE_NULL 字符) 中指定的长度。[in/out] SubsystemName用于...

这条路径上使用clock buffer,并且尺寸不能太小,一般D8、D12、D16就可以。 4.IR-drop问题 该芯片的电源有VDD18、VDD和BLOCK_VDD,其中VDD和top的stdcell以及memory供电,BLOCK_VDD给算核单独供电,但是VDD和BLOCK_VDD都是0.9V的电压。这里踩了一个大坑,由于算核功耗占据了芯片整体功耗的80%,因此BLOCK_VDD需要的...
XSpiPs_PolledTransfer(&SpiInstance, (u8*)&TxBuffer, (u8*)&RxBuffer, 8); This allows us to work with transfer sizes of 8, 16 or 32 bits. To demonstrate this, I connected the SPI master example to a Digilent Digital Discovery to capture the transmitted data. With the data width changed...
