FNC295 – INITER / Initialize ER
Outline
This instruction initializes extension file registers (ER) to "HFFFF" (<K-1>) in a memory cassette (flash memory) before
executing the SAVER (FNC291) instruction.
Because the INITER (FNC295) instruction is not supported in FX
instruction instead.

Explanation of function and operation
1. 16-bit operation (INITER and INITERP)
"n" sectors of extension file registers (ER) in a memory cassette (flash memory) with the same device number as
S
are initialized to "HFFFF" (<K-1>).
Initialization is executed in sectors.
