SPECIAL FUNCTION REGISTERS
(continued)
Stack Pointer (SP)
The Stack Pointer Register is eight bits wide. It is incremented
before data is stored during PUSH and CALL executions.
While the stack may reside anywhere in on-chip RAM, the
Stack Pointer is initialized to 07H after a reset. This causes
the stack to begin at location 08H.
Data Pointer (DPTR)
The Data Pointer consists of a high byte (DPH) and a low
byte (DPL). Its function is to hold a 16-bit address. It may be
manipulated as a 16-bit register or as two independent
8-bit registers.
Ports 0 To 3
P0, P1, P2, and P3 are the SFR latches of Ports 0, 1, 2, and
3, respectively.
Serial Data Buffer (SBUF)
The Serial Data Buffer is actually two separate registers, a
transmit buffer and a receive buffer register. When data is
moved to SBUF, it goes to the transmit buffer, where it is
held for serial transmission. (Moving a byte to SBUF
initiates the transmission.) When data is moved from SBUF,
it comes from the receive buffer.
Timer Registers
Register pairs (TH0, TL0), (TH1, TL1), and (TH2, TL2) are
the 16-bit Counter registers for Timer/Counters 0, 1, and 2,
respectively.
Capture Registers
The register pair (RCAP2H, RCAP2L) are the Capture
registers for the Timer 2 Capture Mode. In this mode, in
response to a transition at the IS80C52/32's T2EX pin, TH2
and TL2 are copied into RCAP2H and RCAP2L. Timer 2
also has a 16-bit auto-reload mode, and RCAP2H and
RCAP2L hold the reload value for this mode.
Control Registers
Special Function Registers IP, IE, TMOD, TCON, T2CON,
SCON, and PCON contain control and status bits for the
interrupt system, the Timer/Counters, and the serial port.
They are described in later sections of this chapter.
