17 MASK OPTIONS FOR P80CL31 AND P80C51
17.1
P80CL31: ROMless version
The P80CL31 is a low voltage ROMless version of the
P80CL51 microcontroller. The mask options for the
P80CL31 are fixed as follows:
Port options: all ports have option “1S”, i.e. standard
port, HIGH after reset
Oscillator option: Oscillator 3
Power-on-reset option: OFF.
17.2
P80C51: 5 V standard version
The P80C51 is a 5 V version of the low voltage P80CL51
microcontroller. All functional features of the P80CL51 are
maintained in the P80C51 with the exception of the mask
options. The mask options on the P80C51 are fixed as
follows:
Port options: all ports have option “1S”, i.e. standard
port, HIGH after reset
Oscillator option: Oscillator 3
Power-on-reset option: OFF.
