Argument(s) |
Description |
|---|---|---|---|---|
otp_get_status |
N/A |
N/A |
N/A |
Reads out the OTP status of user region and status of each field (programmed or not). |
otp_read_params |
N/A |
N/A |
N/A |
Reads out all the OTP parameters (excluding QSPI_KEY which cannot be read). |
otp_write_params |
REGION_PROTECT |
0x100 |
arg |
arg = 0x50FA50FA : Enable R/W permission
arg = 0x00000000 : Lock Region from Writing
arg = Others : Invalid
All four REGION_PROTECT registers are written with this 32-bit argument.
|
otp_write_params |
QSPI_KEY |
0x110 |
arg1 arg2 arg3 arg4 |
All four key arguments are 32-bit values forming the required 128-bit (Q)SPI key for encryption.
For example, if QSPI key is “112233445566778899aabbccddeeff00” then arg1=0x44332211 arg2=0x88776655 arg3=0xccbbaa99 arg4=0x00ffeedd
|
otp_write_params |
MAC_ADDRESS0 |
0x120 |
arg1 arg2 |
If MAC address is AA:BB:CC:DD:EE:FF, then arg1=0xDDCCBBAA and arg2=0xFFEE. |
otp_write_params |
MAC_ADDRESS1 |
0x128 |
arg1 arg2 |
If MAC address is AA:BB:CC:DD:EE:FF, then arg1=0xDDCCBBAA and arg2=0xFFEE. |
otp_write_params |
CALIB_XO |
0x130 |
arg |
arg is 7-bit unsigned XO value. Bits [31:7] unused. Adjusts capacitor bank, 0 : Lowest capacitance (Highest frequency), 127 : Highest capacitance (Lowest frequency). |
otp_write_params |
CALIB_PWR2G |
0x13C |
arg |
arg is 32-bit value specifying maximum output power for DSSS, MCS0, MCS7 (DSSS in bits[7:0] - unsigned). Measured in channel 7. Bits [31:24] unused. |
otp_write_params |
CALIB_PWR5GM7 |
0x140 |
arg |
arg is 32-bit value specifying maximum output power for MCS7 in channel 36, 100, 165 (channel 36 in bits[7:0] - unsigned). Bits [31:24] unused. |
otp_write_params |
CALIB_PWR5GM0 |
0x144 |
arg |
arg is 32-bit value specifying maximum output power for MCS0 in channel 36, 100, 165 (channel 36 in bits[7:0] - unsigned). Bits [31:24] unused. |
otp_write_params |
REGION_DEFAULTS |
0x154 |
arg |
Register default enable control.
arg is 32-bit value where a specific bit is set to
0 implies that the corresponding OTP field is programmed. The following list shows the bit and field mapping:bit 0 : QSPI_KEY
bit 1 : MAC0 Address
bit 2 : MAC1 Address
bit 3 : CALIB_XO
bit 4 : Reserved
bit 5 : Reserved
bit 6 : CALIB_PWR2G
bit 7 : CALIB_PWR5GM7
bit 8 : CALIB_PWR5GM0
bit 9 : Reserved
bit 10 : Reserved
bit 11 : Reserved
bit 12-31 : Reserved
