Integrated circuit and cordless telephone using the integrated circuit. |
摘要 |
An integrated circuit especially suitable for incorporation into the base and handset units of a cordless telephone integrates the speech, control channels, and microcontroller portions of a modem, and the man-machine interface functions of a cordless telephone. The integrated circuit includes one or more of a number of aspects including an in-circuit emulation mechanism, a simplified keypad reporting mechanism, advanced noise suppression mechanisms, a low power emergency mode mechanism, a low cost serial control bus, a port pin interrupt mechanism, advanced power saving mechanisms, spectral measurement test mode means, a novel shut down mechanism, and a pull-up disabling mechanism. |
