B Pointer, located in RAM register memory location 00FE.
Contents of RAM data memory location indicated by B pointer.
Same as [B], except that B pointer is post-incremented.
Same as [B], except that B pointer is post-decremented.
Carry flag, located in bit 6 of the PSW register at memory location 00EF Hex.
Half Carry flag, located in bit 7 of the PSW register at memory location 00EF
Hex.
8-bit memory address for RAM data store memory.
Memory Direct, which may be represented by an implicit label (B, X, SP), a de-
fined label (TEMP, COUNTER, etc.), or a direct memory address (12, 0EF, 027,
etc., where a leading 0 indicates hexadecimal).
Program Counter (15 bits, with a program memory addressing range of 32768).
Program Counter Upper, which contains the upper 7 bits of PC.
Program Counter Lower, which contains the lower 8 bits of PC.
Processor Status Word Register, found at memory location 00EF.
Selected Register (1 of 16) from the RAM data memory at addresses 00F0-00FF.
# the of memory register to be used (# = 0-F hexadecimal).
# symbol is used to indicate an immediate value, with a leading zero (0) indicat-
ing hexadecimal.
Examples:
#045 = immediate value of hexadecimal 45
#45 = immediate value of decimal 45
# may also be used to indicate bit position, where # = 0-7
Example:
RBIT #, [B]
Stack Pointer, located in RAM register memory location 00FD.
X pointer, located in RAM register memory location 00FC.
Contents of RAM data memory location indicated by the X pointer.
Same as [X], except that the X pointer is post-incremented.
Same as [X], except that the X pointer is post-decremented.
