Extended data area access using the CPU bank registers
BX and BY
IX, IY, BX and registers
IX and IY are independent 16-bit registers called index
registers. BX and BY are independent 7-bit registers
called bank registers.
These registers are mainly used to specify memory
addresses and to generate 23-bit addresses. The IX
and IY registers are also used as 16-bit addition
instruction registers.
The BX and BY registers are assigned to address
FFECH (BX register) and address FFEDH (BY) in the
built-in input/output register area. Only the lower 7 bits
of these registers are effective; the uppermost bit is
undefined. This undefined bit is always read as “1”.
The lower 7 bits of the BX and BY registers are initialized to
“0” by resets.
Extended data area addressing mode
The TMP90C051F can use up to 8M bytes of data
memory.
Addresses 0000000H - 00FFFFH can be accessed in
the normal addressing mode.
Addresses 010000H - 7FFFFFH are called the
extended data area and are accessed in a special
addressing mode.
To access the extended data area, an addressing
mode (a mode that uses the register indirect addressing
mode register pair IX or IY, or a mode that uses the
index addressing mode register pair IX or IY) that uses
the index addressing mode register pair IX or IY to calculate
the operand address.
Thus, there are four types.
(IX)
(IY)
(IX + d)
(IY + d)
In these modes, the 23-bit address required for
accessing the extended data area consists of a 16-bit
offset (address bus A0 - A15) and a 7-bit bank
address (address bus A16 - A22).
The 16-bit offset is the same as the calculated value of
the conventional address.
The 7-bit bank address is specified with bank register
BX or BY. BX is used to form a pair in modes that use
the index register IX. BY is used to form a pair in
modes that us the index register IY.
Note:
When the extended data area addressing
mode is used with the JR or CALL instruc-
tion, the value of the bank register that cor-
responds to that index register must be “0”.
These instruction cannot use in expand memory area
at MMU.
