OTP Read (OTPR 4Bh)
ASP Read (ASPRD 2Bh)
The OTP Read command reads data from the OTP region. The OTP region is 1024 bytes so, the address bits
from A23 to A10 must be zero for this command. Refer to
OTP region. The protocol of the OTP Read command is similar to the Fast Read command except that it will
not wrap to the starting address after the OTP address is at its maximum; instead, the data beyond the
maximum OTP address will be undefined. Also, the OTP Read command is not affected by the latency code.
The OTP read command always has one dummy byte of latency as shown below.
The ASP Read instruction 2Bh is shifted into SI by the rising edge of the SCK signal. Then the 16-bit ASP
register contents is shifted out on the serial output SO, least significant byte first. Each bit is shifted out at the
SCK frequency by the falling edge of the SCK signal. It is possible to read the ASP register continuously by
providing multiples of 16 clock cycles. The maximum operating clock frequency for the ASP Read (ASPRD)
command is 133 MHz.
