I would like to ask about the relationship between the BootMode pin setting and the internal BootMode register.
I checked the internal BootMode register value against the Primary BootMode pin setting.
In the cases shown below, Why is it different from pin setting?
(Case-1)
Pin Setting (Primary BootMode = Ethernet RGMII)
MCU_BOOTMODE[9:0] = 11_0010_0000 , BOOTMODE[7:0] = 1000_1110
==> RegisterValue (Primary BootMode =UART)
MCU_BOOTMODE[9:0] = 11_0011_1000 , BOOTMODE[7:0] = 1000_1110
(Case-2)
Pin Setting (Primary BootMode = Ethernet RMII)
MCU_BOOTMODE[9:0] = 11_0010_1000 , BOOTMODE[7:0] = 1000_1110
==> RegisterValue (Primary BootMode =UART)
MCU_BOOTMODE[9:0] = 11_0011_1000 , BOOTMODE[7:0] = 1000_1110
In other cases, register value matches the pin-setting.
Regards,
