RAMWRFST14

0: Write to area 14 by DMA

R (Note 1)

(Area 14 RAM write source status bit)

1: Write to area 14 by CPU, SDI, or NBD

RAMWRFST15

0: Write to area 15 by DMA

R (Note 1)

(Area 15 RAM write source status bit)

1: Write to area 15 by CPU, SDI, or NBD

Note 1: Only writing "0" is effective. Writing "1" has no effect; the bit retains the value it had before the write.

If the CPU, SDI (tool), or NBD attempted to access any area for write that is “disabled against write” by the RAM

Write Disable Control Register, the corresponding bit in this register is set to "1." After setting the bit to "1," the bit

is not cleared to "0" if a DMA write access occurred. The bit is cleared by writing a "0" in software. Writing a "1" to

any bit in this register has no effect, so the bit retains the value it had before the write.
