Register Field:
5.6.2.8.8 Read Memory Location (READ). Read the sized data at the memory location
specified by the long-word address. Only absolute addressing is supported. The SFC
register determines the address space accessed. Valid data sizes include byte, word, or
long word.

Result Data:
5.6.2.8.9 Write Memory Location (WRITE). Write the operand data to the memory
location specified by the long-word address. The DFC register determines the address

The system control register is specified by the register field (see Table 5-24). The FAR
is a read-only register—any write to it is ignored.
The single operand is the long-word address of the requested memory location.
The requested data is returned as either a word or long word. Byte data is returned in
the least significant byte of a word result, with the upper byte cleared. Word results
return 16 bits of significant data; long-word results return 32 bits.
A successful read operation returns data bit 16 cleared. If a bus or address error is
encountered, the returned data is $10001.
