Part Number: 66AK2H06 Hi, I got below questions from my customer for device power-up and power-down sequence. Customer follows the sequence in datasheet. Q1) At power-up, as soon as CVDD is on, it seems some voltage leakage is observed on 1.8V and 0…
Part Number: 66AK2H06 Hi,
What does below code mean in arm rom code?
0x2501040 + (core number<<3)
0x1000030 + (core number<<2)
0x100_0030 is the address of AXI2BUSM Master.
Part Number: 66AK2H06 Hi, Customer wants to know capacitance value(Cp) for SPI pins. (This affects the maximum frequency for an external SPI flash) Our datasheet only provides Cp for I2C pins. Thanks and regards, Koichiro Tashiro
Tashiro-san,
Since there have been no responses, I will close this thread. If you want to re-open it, simply post to this thread. If it becomes lockec, you can open a new thread and link them together.
