a and b of Fig.57.
Depending on the series resistance in the supply wires, up to 16 OTP bits can be programmed at the same time. Each
OTP cell can only be programmed once.
Table 98 Programming specification (see Fig.57)
Note
1. The voltage drop across the ITO track and any connector must be taken into account to guarantee a sufficiently high
