7.3.3 OTP Mode

In this mode, the configuration pins allow for selection of one of four one-time programmable (OTP) pages, as well as output format selection. I2C is not enabled in this mode, as the I2C pins are repurposed for OTP page selection. Table 7-2 shows the OTP page selected based on the state of the OTP_SEL0 and OTP_SEL1 pins. In OTP mode, the FMT_ADDR pin is ignored by default. This is overridden if R9[8] = 1 is burnt into the OTP in the configuration. Otherwise, the output format is determined by Table 7-3.

Table 7-2 OTP Page Selection in OTP Mode
OTP_SEL1 Pin OTP_SEL0 Pin OTP Page

0 X Set by R6[2:0] / R7[4:2]
1 GND LP-HCSL 100 Ω Termination
1 VDD LP-HCSL 85 Ω Termination

The EFUSE of the devices is permanently programmed and has R0[0] = 1. If a new configuration is desired, the configuration must be loaded through I2C on each start-up.

The following fields can be unique between the four OTP pages. All other register settings are shared between the OTP pages:
