Returns This the is number an of internal bytes call of for non-volatile OS memory use available. only Bytes and 0-15 should not be used by user software.
should be included in the count, so for example a Philips PCF8583 CMOS/RTC
device (as used in the Archimedes and Risc PC) would be described as a
256-byte device, with locations 0-15 not readable. More complex arrangements
would have to be abstracted out by the HAL providing its own NVMemory access
calls.

More complex arrangements would have to be abstracted out by the HAL providing its own NVMemory access calls.
This is to suit the current RISC OS Kernel, which does not use bytes 0-15.
