<p>
Description: Reads a specified flash block to a buffer in RAM.<p>
BlockID is converted to absolute address and then ROMX command is used to read the data from flash into the specified buffer. (See flash.asm for more info)<p>
Uses SSC storage at FBh and FDh<p>
Inputs:<ul>
<li>BYTE - Flash block ID</li><li>void* - Destination RAM location</li><li>BYTE - Number of bytes to read</li></ul>
<p>
Returns:<ul>
<li>Data read is returned at specified RAM location. </li></ul>

<p>
Description: Writes 64 bytes of data to the flash at the specified blockId. Regardless of the size of the buffer, this routine always writes 64 bytes of data. If the buffer is less than 64 bytes, then the next 64-N bytes of data will be written to fill the rest of flash block data. (See flash.asm for more info)<p>
1 ) Compute the pulsewidths 2 ) Erase the specified block 3 ) Program the specified block<p>
Uses RAM locations 0xFB and 0xFD<p>
Assumptions: Single block Write CPU clock is 12MHz Temperature is defined to be 32 degees celcius<p>
Inputs:<ul>
<li>BYTE - Flash block ID</li><li>void* - Source RAM location</li></ul>
<p>
Returns: SSC_RETURNCODE </td>
