Module freqa

source
Expand description

The FREQA & FREQB registers control the frequency by controlling the drive strength of each stage
The drive strength has 4 levels determined by the number of bits set
Increasing the number of bits set increases the drive strength and increases the oscillation frequency
0 bits set is the default drive strength
1 bit set doubles the drive strength
2 bits set triples drive strength
3 bits set quadruples drive strength

Enums§

  • PASSWD_A
    Set to 0x9696 to apply the settings
    Any other value in this field will set all drive strengths to 0
