| zero | 0 | woWrite-only | 0x0 | Writing 1 zeroes the write buffer (this bit is self-clearing). Can be used to avoid writing the zero-value LSB bytes of the word. For example, to write one or more all-zero words, the CPU shall write a 1 to this register, then commit the write buffer to the memory addresses through one or more write to the RSA_WR_ADDR register. To write the word with zero LSB bytes, the CPU shall write a 1 to this register, then write the non-zero MSB bytes to the RSA_WR_DATA register (starting with the least significant one), then commit the buffer by writing the memory address to the RSA_WR_ADDR register. |
