Sourcepub fn ecc_calcr2(self) -> RegisterFieldBool<31, 1, 0, EccCommandReg_SPEC, RW>
pub fn ecc_calcr2(self) -> RegisterFieldBool<31, 1, 0, EccCommandReg_SPEC, RW>
This bit indicates if the IP has to calculate R mod N for the next operation. This bit must be set to 1 when a new prime number has been programmed. This bit is automatically cleared when R mod N has been calculated. ‘0’: no effect ‘1’: forces the IP to re-calculate R mod N
Sourcepub fn ecc_signb(self) -> RegisterFieldBool<30, 1, 0, EccCommandReg_SPEC, RW>
pub fn ecc_signb(self) -> RegisterFieldBool<30, 1, 0, EccCommandReg_SPEC, RW>
Sign of parameter B in equation y2=x3+Ax+B ‘0’: B is positive ‘1’: B is negative
Sourcepub fn ecc_signa(self) -> RegisterFieldBool<29, 1, 0, EccCommandReg_SPEC, RW>
pub fn ecc_signa(self) -> RegisterFieldBool<29, 1, 0, EccCommandReg_SPEC, RW>
Sign of parameter A in equation y2=x3+Ax+B ‘0’: A is positive ‘1’: A is negative
Sourcepub fn ecc_sizeofoperands(
self,
) -> RegisterField<8, 0xff, 1, 0, u8, u8, EccCommandReg_SPEC, RW>
pub fn ecc_sizeofoperands( self, ) -> RegisterField<8, 0xff, 1, 0, u8, u8, EccCommandReg_SPEC, RW>
This field defines the size (= number of 64-bit double words) of the operands for the current operation. Possible values are limited by the generic parameter g_Log2MaxDataSize that defines the max space allocated or reserved to each operand.
Arbitrary Data/Key size from 128 up to 2566 are supported: 0x02 (02d) -> 128-bit Data/Key size 0x03 (02d) -> 256-bit Data/Key size ECC-ECDSA - Prime Field F(p) 0x03 -> 192-bit (Curve P-192) 0x04 -> 256-bit (Curves P-224 & P-256) ECC-ECDSA - Binary Field F(2m) 0x03 -> 192-bit (Curve K-163) 0x04 -> 256-bit (Curve K-233)
- 4 Xers: 0x01, 0x02, 0x4, 0x6 -> 64, 128 & multiples of 128 bits
Sourcepub fn ecc_field(self) -> RegisterFieldBool<7, 1, 0, EccCommandReg_SPEC, RW>
pub fn ecc_field(self) -> RegisterFieldBool<7, 1, 0, EccCommandReg_SPEC, RW>
‘0’: Field is F(p) ‘1’: Field is F(2m)
