W77IC32
- 12 -
This is the high byte of the new additional 16-bit data pointer that has been added to the W77IC32. The
user can switch between DPL, DPH and DPL1, DPH1 simply by setting register DPS = 1. The
instructions that use DPTR will now access DPL1 and DPH1 in place of DPL and DPH. If they are not
required they can be used as conventional register locations by the user.

DPS.0
Mnemonic: DPS
Address: 86h
DPS.0: This bit is used to select either the DPL,DPH pair or the DPL1,DPH1 pair as the active Data
Pointer. When set to 1, DPL1,DPH1 will be selected, otherwise DPL,DPH will be selected.
DPS.1-7:These bits are reserved, but will read 0.

Mnemonic: PCON
Address: 87h
SMOD : This bit doubles the serial port baud rate in mode 1, 2, and 3 when set to 1.
SMOD0: Framing Error Detection Enable: When SMOD0 is set to 1, then SCON.7(SCON1.7) indicates
a Frame Error and acts as the FE(FE_1) flag. When SMOD0 is 0, then SCON.7(SCON1.7)
acts as per the standard 8052 function.
GF1-0: These two bits are general purpose user flags.
PD:
Setting this bit causes the W77IC32 to go into the POWER DOWN mode. In this mode all the
clocks are stopped and program execution is frozen.
IDL:
Setting this bit causes the W77IC32 to go into the IDLE mode. In this mode the clocks to the
CPU are stopped, so program execution is frozen. But the clock to the serial, timer and
interrupt blocks is not stopped, and these blocks continue operating.

Timer 1 overflow flag: This bit is set when Timer 1 overflows. It is cleared automatically when
the program does a timer 1 interrupt service routine. Software can also set or clear this bit.
Timer 1 run control: This bit is set or cleared by software to turn timer/counter on or off.
Timer 0 overflow flag: This bit is set when Timer 0 overflows. It is cleared automatically when
the program does a timer 0 interrupt service routine. Software can also set or clear this bit.
Timer 0 run control: This bit is set or cleared by software to turn timer/counter on or off.
