Code:
1Fh 28h 65h 19h sL sH sE m1 a1L a1H a1E m2 a2L a2H a2E
sL:
Transfer size, lower byte
sH:
Transfer size, upper byte
sE:
Transfer size, extension byte
m1:
Destination memory select
a1L:
Destination address, lower byte
a1H:
Destination address, upper byte
a1E:
Destination address, extension byte
m2:
Source memory select
a2L:
Source address, lower byte
a2H:
Source address, upper byte
a2E:
Source address, extension byte
Definable area:
m1, m2 = 30h (General-purpose RAM):
000001h ≤ (sL + sH×100h + sE×10000h) ≤ 000400h
000000h ≤ (a1L + a1H×100h + a1E×10000h) ≤ 0003FFh
000000h ≤ (a2L + a2H×100h + a2E×10000h) ≤ 0003FFh
m1, m2 = 31h (General-purpose FROM):
000001h ≤ (sL + sH×100h + sE×10000h) ≤ 001000h
000000h ≤ (a1L + a1H×100h + a1E×10000h) ≤ 00FFFFh
000000h ≤ (a2L + a2H×100h + a2E×10000h) ≤ 00FFFFh
Note: General-purpose FROM is in units of 001000h, with a total of 16 areas.
Function:
Transfer data between general-purpose memory areas.
Storage that would exceed the address range cannot be set.
For General-purpose RAM, data is transferred only into the specified address range.
For General-purpose FROM, data is transferred into the specified address range, and all other
memory locations in the same FROM area are set to FFh. Further, it is not possible to specify data
transfer that would exceed a general-purpose FROM area.
Operation is not guaranteed if source and destination areas overlap.
This command is valid in both User setup mode and Normal mode.
