EEPMOV (MOVe data to EEPROM)
Operand Format and Number of States Required for Execution
Note: * n is the initial value of R4. Although n bytes of data are transferred, 2(n + 1) data accesses are
Notes
This instruction first reads memory at the addresses indicated by ER5 and ER6, then carries out
the block data transfer.
EEPMOV.W Instruction and Interrupt
If an interrupt request occurs while the EEPMOV.W instruction is being executed, interrupt
exception handling is carried out after the current byte has been transferred. Register contents are
then as follows:
ER5: address of the next byte to be transferred
ER6: destination address of the next byte
R4:
The program counter value pushed on the stack in interrupt exception handling is the address of
the next instruction after the EEPMOV.W instruction. Programs should be coded as follows to
allow for interrupts during execution of the EEPMOV.W instruction.
Example:
L1: EEPMOV.W
Interrupt requests other than NMI are not accepted if they are masked in the CPU.
During execution of the EEPMOV.B instruction no interrupts are accepted, including NMI.
