When using the internal RAM:
R0–32767 (32768) with block conversion in steps of
32768 registers, 65536 (for Q02UCPU) resp. 98304 (for
Q03UD(E)CPU) file registers are accessible.
When using a 1 MB SRAM memory card:
With block conversion in steps of 32768 registers,
517120 file registers are accessible.
When using a 2 MB Flash or 2 MB SRAM memory card:
With block conversion in steps of 32768 registers,
1040384 file registers are accessible.
When using a 4 MB Flash or 4 MB SRAM memory card:
With block conversion in steps of 32768 registers,
2087936 file registers are accessible.
When using a 8 MB SRAM memory card:
With block conversion in steps of 32768 registers,
4184064 file registers are accessible.
Extension of the data register area
When using a Flash memory card only
reading of the file registers is possible.
It’s not possible, to use an ATA memory
card.
