Properties

init

readonly init: number

Defined in: checksum/crc-types.ts:11

The register’s value before the first byte is read.

---

polynomial

readonly polynomial: number

Defined in: checksum/crc-types.ts:9

The generating polynomial, MSB-first, with the top (implicit) bit omitted.

---

refIn

readonly refIn: boolean

Defined in: checksum/crc-types.ts:13

true if each input byte is consumed least-significant-bit first.

---

refOut

readonly refOut: boolean

Defined in: checksum/crc-types.ts:15

true if the register is bit-reversed before xorOut is applied.

---

width

readonly width: 8 | 16 | 32

Defined in: checksum/crc-types.ts:7

Register width in bits.

---

xorOut

readonly xorOut: number

Defined in: checksum/crc-types.ts:17

XORed into the register after every byte has been read and any refOut.
