Message: | prod/doc/: added marked-up layout to indicate CLKM/CLK test points - atben.fig, atusb.fig: layout images overlaid by markup - Makefile: added images derived from atben.fig and atusb.fig - Makefile: added generation of the layout images atben.fig and atusb.fig are based on - analysis.html: show measurement locations for CLKM and CLK |

104 | 104 | We can therefore consider all results within a range of +/− 1000 ppm as |
105 | 105 | sufficient, and perform more precise measurements by other means. This |
106 | 106 | applies to <B>atben</B> as well as to <B>atusb</B>. |

120 | 119 | This configures <B>atben</B> as a promiscuous receiver. The reception |
121 | 120 | of any IEEE 802.15.4 frame or pressing Ctrl-C will terminate the command. |
122 | 121 | <P> |
122 | The clock signal (CLKM) is available on the test pad shown here: | |

142 | 145 | of reset, it raises the transceiver's clock output to 8 MHz and then |
143 | 146 | enables USB. |
144 | 147 | <P> |
148 | The clock signal is available at the terminals of several components, | |
149 | either as the direct output from the transceiver (CLKM) or after passing | |
150 | a low-pass filter (CLK): | |
