A memory block, whose size is shown by size, is transferred from the
address specified by src to the address specified by dst. The eepromb
intrinsic function transfers a memory block with the EEPMOV.B instruction,
and eepromw with the EEPMOV/P.W instruction.
These intrinsic functions sets dst, src and size to the registers, sets ecrval to
the address pointed by ecr, and then transfers the memory block.
If transfer completes successfully, 0 is returned. If transfer fails, the
remaining size of the memory block left is returned. size of eepromb can
take 0 to 255, and size of eepromw can take 0 to 65535. However, if size is 0,
no transfer occurs.

This intrinsic function is valid only when the CPU type is AE5 or
H8SX and the -eeprom option is specified.
To use these intrinsic functions by specifying the CPU type other than
AE5, the eeprom option must be specified at compilation.
Refer to the hardware manual for the details of ECR, EPR, and other
related issues.
