Macro Definition Documentation

#define TM_OTP_BlockLocked ( block ) ((*(__IO uint8_t *) (OTP_LOCK_ADDR + block)) == 0x00 ? 1 : 0)

Checks if block is locked or not.

Parameters

block OTP block number, 0 to 15 is allowed

Return values

Block

lock status

TM_OTP_Result_t TM_OTP_BlockLock ( uint8_t block )

Locks entire block to prevent future programming inside.

Note: When you lock your block, then you are not able to program it anymore. Even, if it is totally empty. You can't unlock it back!

Parameters

block OTP block number, 0 to 15 is allowed

Return values

Member of TM_OTP_Result_t enumeration

Reads data from specific block and specific byte in this block.

Parameters

block	OTP block number, 0 to 15 is allowed
byte	OTP byte inside one block, 0 to 31 is allowed

Return values

Value at specific block and byte location, or 0 if location is invalid

Writes one-time data to specific block and specific byte in this block.

Note: You can only ONCE write data at desired byte in specific block, if you will try to do it more times, you can have broken data at this location.

Parameters

block	OTP block number, 0 to 15 is allowed
byte	OTP byte inside one block, 0 to 31 is allowed
data	Data to be written to OTP memory

Return values

Member of TM_OTP_Result_t enumeration
