Hi, Has anybody here the usermanual for the p89lpc9408 ? And willing to share :-) Thanks, roelof |

"The P89LPC9408 is a multi-chip module consisting of a P89LPC938 single-chip microcontroller combined with a PCF8576D universal LCD controller" Can't the two respective constituents' manuals be used, then? JW > >Has anybody here the usermanual for the p89lpc9408 ? >And willing to share :-) |

That is what I have been doing but I was hoping for a user manual for the lpc9408 with all data combined :-) roelof |

>First hit on Google search: > >http://www.keil.com/dd/docs/datashts/philips/lpc9408_ds.pdf That's the datasheet. Confusingly maybe, Philips/NXP uses the two-document scheme: datasheet (description of electrical, mechanical and sometimes part-specific properties) + (user) manual (functional description). Roelof is looking for the latter. JW PS. Roelof, you might try to ask on 8052.com's forum, too. |

Texas instruments does that too. Anything is better then the documentation mess at Freescale (if I remember correctly), they might have improved it by now..... I have no problems with the way nxp and ti do it. > Roelof is looking for the latter. > > > JW > > PS. Roelof, you might try to ask on 8052.com's forum, too. It is not super important to me to have an user manual specifically for the lpc9408. I can do with the lpc938 um and the pcf8576 datasheet. I do not like the 8052.com forum so I do not go there often, once a year maybe. Thanks any way. roelof |

I fail to see what is missing in this datasheet, it handles all the features including bitfields for the registers, detailed description of the things like the PWM, timers and LCD stuff.. For example page 44, 7.27.2 labeled 'functional description' explains in detail how the LCD controller is working. Gert |

The pcf8576 datasheet explains all the rest you (I) need to know :-) The thing is, why I asked for an um for the lpc9408, is that for instance the hex address of the keypad pattern register is missing from the table on page 13. And I have not looked at the ADC in detail yet but I had some doubts about the extended registers for it and wanted to check that against the specific um of the lpc9408. Yes, I know it is the lpc938 processor but I still wanted to check. I hope my intensions are clear now :-) roelof ps. The address of kbpatn (0x93) is in the p89lpc938.h file included with sdcc in sdcc/share/sdcc/include/mcs51/ Did not check it yet against the silicon. |
