Program counter
The PC is a 13-bit counter that indicates the address in program memory (ROM) of the next instruction to execute.
Normally the PC is incremented on every instruction cycle in the range 000H to 1F7FH. (Addresses in the range 1F80
to 1FFF are reserved for testing and cannot be used by user programs.) However, data values are loaded into the PC
by the execution of branch and subroutine instructions and on the occurrence of interrupts or an initial reset. The table
below describes the data loaded for these operations.
Page:
the ROM page flags, which take 2048 locations as a single page
The page is specified with the MROPF and SROPF instructions.
P00 to P10: Bits in the instruction code (i.e., immediate data)
Program memory
The ROM memory consists of 4096 x 16 bits (4 kwords or 8 kbytes) in the LC587004, 6144 x 16 bits (6 kwords or 12
kbytes) in the LC587006 and 8064 x 16 bits (8 kwords or 16 kbytes) in the LC587008. ROM hold user programs to be
executed.
Data memory
These microprocessors provide an on-chip RAM that consists of 512
×
4 bits (2 Kb). This RAM is accessed as two
256
×
4-bit pages.
RAM addresses can be specified in four ways as listed below.
Directly specified at 00H to FFH (immediate addressing)
Indirect specification using the 8-bit data pointer.
Indirect specification by the 4-bit RAM bank register multiplied by 10H plus immediate data in the range 0 to FH.
Indirect specification by the 4-bit RAM bank register multiplied by 10H plus 8H plus immediate data in the range 0 to
FH.
Writing to RAM is always performed through the accumulator.
