| |
The TA_PROG_SFP supply must be enabled to program the fuses, and disabled to read the fuses (such as at power-on-reset). On many boards, this supply is controlled by a jumper. The user must manually insert or remove it at the appropriate time in the programming process. However, on other boards this supply is controlled by an FPGA or a GPIO. In these cases, the driver can automatically enable and disable it as necessary.
