#189915 - also try CLKREG Responding to: ???'s previous message |

Using this code, I get 2.53mA with the ceramic resonator, and 2.41mA with the internal clock. Also try the LP214 CLKREG clock divider. the LP series are pretty much MHz linear, so a /16 here, will buy you a 1/16 in slope current, and let you find the ~origin-intercept Idd. CLKREG = [ TPS3 TPS2 TPS1 TPS0 – CDV1 CDV0 COE] CDIV1 CDIV0 Clock Out Frequency 0 0 f/2 0 1 f/4 1 0 f/8 1 1 f/16 See the LP52 for a diagram of how CDIV works (LP52 has more choices but the flow is the same). |
