It includes the following major -components: (a) 256k SRAM (km681000l), (b) 256 EPROM (27C010), -(c) DP8570A (clock/timer/calendar), (d) MAX791 (cpu supervisory chip -with battery backup switch-over and watch dog timer), and -(e) NS16550DN (UART). The following interrupt functions have also been -incorporated: UART, TIMER, Watch Dog, and Low Line voltage (trips at -4.85V; enough time to save the cpu reg before reset is asserted on -power down). - The schematic for efi68k is freely available via e-mail. Send -"index diy_efi" to majordomo@coulomb.eng.ohio-state.edu. Retrieve the -files related to 68hc000-1.00 with the "get diy_efi <filename>" -command. efi68k does not have an available printed circuit board, but -can be wire-wrapped in about four days. Cost is about $100US. - -TODO: -===== -- add the "tm27 vector" ... can we use a trap instruction? -- generate include/coverhd.c to perform the tmtest. -- the interrupt drive I/O should be integrated into the RTEMS. -- finish the ROM memory model. -- add separate interrupt stack (low priority). - - John S Gwynne - Gwynne.1@osu.edu -_______________________________________________________________________________ - T h e O h i o - S t a t e U n i v e r s i t y - ElectroScience Laboratory, 1320 Kinnear Road, Columbus, Ohio 43212, USA - Telephone: (614) 292-7981 * Fax: (614) 292-7297 -------------------------------------------------------------------------------- - |
