Data Sheet
SDLC COMMUNICATIONS CONTROLLER
The state of bits RS1, RS0 selects the working registers bank as follows:
RS1/0
Bank selected location
00
Bank 0 (00H – 07H)
01
Bank 1 (08H – 0FH)
10
Bank 2 (10H – 17H)
11
Bank 3 (18H – 1FH)
Stack Pointer (SP):
The Stack Pointer is a 1-byte register initialized to 07H after reset. This register is incremented
before PUSH and CALL instructions, causing the stack to begin at location 08H. The stack pointer
points to a location in internal RAM.

Data Pointer (DPTR):
The Data Pointer (DPTR) is 2 bytes wide. The lower part is DPL, and the highest is DPH.
It can be loaded as 2 byte register (MOV DPTR,#data16) or as two registers (ea. MOV
DPL,#data8). It is generally used to access external code or data space (ea. MOVC
A,@A+DPTR or MOV A,@DPTR respectively).
