[Explanation]
FMOV
O D S n ;
(1) The constant or contents for device specified with (S) are batch-transferred to the
n words from the device specified with (D). (Transferred with 1-word [16-bit] unit.)
(2) Data can be transferred if the word devices of the transfer source and destination
overlap.
(3) When the H+32-bit hexadecimal constant for (D) is specified, it is meant to specify
the absolute address of the Motion CPU. The absolute address specifies the even
number.
When the absolute address is specified, the content of the address is understood.
When a wrong operation is executed, operation which crashes the system, and is
abnormal might be executed.
(4) When a wrong operation is executed, operation which crashes the system, and is
abnormal might be executed.
(a) (S) is outside the range -32768 to 65535. (When constant specified)
(b) When (S) is outside the range of the device. (When indirectly specified device)
(c) When from (D) to (D)+(n-1) is outside the range of the device.
(d) (n) is outside the range 1 to 65535. (When constant specified)
(e) When (n) is outside the range of the device. (When indirectly specified device)
(f) When the absolute address is outside the range of RAM.
The data of n words from the specified device are batch-transferred to
the specified transfer destination. (a word [16-bit] unit)
Number of transmission words
(Constant or indirect setting (1 to 65535))
Transfer source data
constant or indirect setting (0 to 65535)
First devices of transfer destination data or
absolute address.
