Description
Specifies the device type
High speed crystal/res., 1MHz…75MHz *
High speed crystal/res., 1MHz…50MHz *
High speed crystal/res., 1MHz…50MHz *
Normal crystal/res., 1MHz…24MHz *
Normal crystal/res., 32kHz…10MHz *
Low power crystal/res., 32kHz…1MHz *
Low power crystal/resonator, 32kHz *
External RC circuit
Specifies internal oscillator @ 4MHz
Specifies internal oscillator @ 1 MHz
Specifies internal oscillator @ 128 kHz
Specifies internal oscillator @ 32 kHz
Disables the internal feedback resistor, i.e. an external feedback resistor is
required between the OSC1 and OSC2 pins
Disables the crystal drive (on OSC2 pin). Use this option to lower power
consumption when using a crystal-oscillator-pack connected only to OSC1
pin.
Brownout to trigger at < 4.2 volts
Brownout to trigger at < 2.6 volts
Brownout to trigger at < 2.2 volts
Specifies turbo mode (1:1 execution)
Stack is extended to 8 levels and Option register is extended to 8 bits
ADD and SUB instructions use Carry flag as input*
