count (cont)

Number of internal-
RAM access for
operand fetch
(READ) (XY-RAM or
O-L memory)

XLR

The number of accesses to XY
memory in the SH7362 during
memory access (read) of an
operand.
(Accesses via the XY bus and
the operand bus are included.
When MOVX and MOVY are
executed simultaneously, it
increments one count
regardless of the read or write.)

Number of internal-
RAM access for
operand fetch
(WRITE) (XY-RAM
or O-L memory)

XLW

The number of accesses to XY
memory in the SH7362 during
memory access (write) of an
operand.
(Accesses via the XY bus and
the operand bus are included.
When MOVX and MOVY are
executed simultaneously, it
increments one count
regardless of the read or write.)

Number of I-L
memory access for
operand fetch
(READ/WRITE)

ILRW

The number of accesses to I-L
memory in the SH7362 during
memory access (read/write) of
an operand.

Number of U-RAM
access (READ)

The number of U-memory
accesses during memory
access (read) of an operand.
(Accesses via the cache are
not included.)

Number of U-RAM
access (WRITE)

The number of U-memory
accesses during memory
access (write) of an operand.
(Accesses via the cache are
not included.)
