Access

Table 52. UF_REGION_R - UF region selection register (address 15h) bit allocation

The user OTP regions UF0, UF1, and F share a block of 16 registers. Prior to reading the

registers via any communication interface, the user must ensure that the desired OTP

registers are loaded into the readable registers. Below is the necessary procedure to

ensure proper reading of the UF0, UF1, and F registers.

1. Write the desired address range to be read to the REGION_LOAD[3:0] bits in the

UF_REGION_W register.

REGION_LOAD[3:0]

OTP register addresses loaded into the readable registers

not applicable

0010 through 1001

reserved

Address Range A0h through AFh

Address Range B0h through BFh

Address Range C0h through CFh

Address Range D0h through DFh

Address Range E0h through EFh

Address Range F0h through FFh

Table 53. REGION_LOAD Bit Definitions

2. Add a delay of minimum 50 µs.

3. Optional: Execute a register read of the UF_REGION_R register and confirm the

REGION_ACTIVE[3:0] bits match the values written to the REGION_LOAD[3:0] bits

in the UF_REGION_W register.

REGION_ACTIVE[3:0]

OTP register addresses loaded into the readable registers

Load of OTP registers is in process

The contents of the shared registers has been over-written by

the user

0010 through 1001

not applicable

Address Range A0h through AFh

Address Range B0h through BFh

Address Range C0h through CFh

Address Range D0h through DFh

Address Range E0h through EFh

Address Range F0h through FFh

Table 54. REGION_ACTIVE Bit Definitions

4. Execute a Register Read of the desired registers from the UF0, UF1 or F register

section. Complete all desired Register Reads of the selected UF Region.

5. Repeat steps 1 through 4 for the next desired UF region to read.
