Software can use this flag to make save/restore more efficient (skip if not DIRTY).<br />
|

|

If the flag is used in this way, it’s recommended to either read QUOTIENT only,<br />
|

|

or REMAINDER and then QUOTIENT, to prevent data loss on context switch.</div></li><li><div class="item-name"><a class="type" href="type.R.html" title="type rp2040_pac::sio::div_csr::R">R</a></div><div class="desc docblock-short">Register <code>DIV_CSR</code> reader</div></li><li><div class="item-name"><a class="type" href="type.READY_R.html" title="type rp2040_pac::sio::div_csr::READY_R">READY_R</a></div><div class="desc docblock-short">Field <code>READY</code> reader - Reads as 0 when a calculation is in progress, 1 otherwise.<br />
