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.
Specifies the calibration value for the
internal RC oscillator, options are
IRC_SLOW, IRC_4MHZ and IRC_FAST
Brownout to trigger at < 4.2 volts
Brownout to trigger at < 2.6 volts
Brownout to trigger at < 2.2 volts
Disable Brownout reset
ADD and SUB instructions use Carry flag as input*
Enable input syncing
Enable the watchdog timer
Enable code protection
Enable clock generation during sleep
