31 to 29 — All 0 R Reserved
For read/write in these bits, refer to General
Precautions on Handling of Product.
28 to 10 L1SADR Undefined R/W L Memory Page 1 Block Transfer Source Address
When MMUCR.AT = 0 or RAMCR.RP = 0, these bits
specify transfer source physical address for block
transfer to page 1 in the L memory.
9 to 6 — All 0 R Reserved
For read/write in these bits, refer to General
Precautions on Handling of Product.
5 to 0 L1SSZ Undefined R/W L Memory Page 1 Block Transfer Source Address
Select
When MMUCR.AT = 0 or RAMCR.RP = 0, these bits
select whether the operand addresses or L1SADR
values are used as bits 15 to 10 of the transfer source
physical address for block transfer to page 1 in the L
memory. L1SSZ bits [5:0] correspond to the transfer
source physical addresses [15:10].
0: The operand address is used as the transfer source
physical address.
1: The L1SADR value is used as the transfer source
physical address.
Settable values:
111111: Transfer source physical address is specified
in 1-Kbyte units.
111110: Transfer source physical address is specified
in 2-Kbyte units.
111100: Transfer source physical address is specified
in 4-Kbyte units.
111000: Transfer source physical address is specified
in 8-Kbyte units.
110000: Transfer source physical address is specified
in 16-Kbyte units.
100000: Transfer source physical address is specified
in 32-Kbyte units.
000000: Transfer source physical address is specified
in 64-Kbyte units.
Settings other than the ones given above are
prohibited.
