DS90UB948-Q1: What needs to be done for locked

洋赵

Part Number: DS90UB948-Q1

1. Can I just provide PCLK to be locked?

2. How to configure 941 internal clock output?
What registers are configured when the internal clock switches to the external clock?

Hi customer,

Are you asking how to PCLK would be locked ? There isn't any read register or configuration to lock for PCLK.
If you want to know auto switch configuration of PCLK, please refer to GENEARL_CFG register 0x3 [1]. If you want to know the detection status of Link or PCLK, please refer to GENERAL_STS register 0xC.
