The driver routines are not -written for any specific operating system. -They serves the purpose of code sample, and -jump-start for using the MPC8240 EPIC unit. - -For the reason of correctness of C language -syntax, these files are compiled by Metaware -C compiler and assembler. - -ENDIAN NOTATION: - -The algorithm is designed for big-endian mode, -software is responsible for byte swapping. - -USAGE: - -1. The host system that is running on MPC8240 - shall link the files listed here. The memory - location of driver routines shall take into - account of that driver routines need to run - in supervisor mode and they process external - interrupts. - - The routine epic_exception shall be called by - exception vector at location 0x500, i.e., - 603e core external exception vector. - -2. The host system is responsible for configuring - the MPC8240 including Embedded Utilities Memory - Block. All EPIC driver functions require the - content of Embedded Utilities Memory Block - Base Address Register, EUMBBAR, as the first - parameter. - -3. Before EPIC unit of MPC8240 can be used, - initialize EPIC unit by calling epicInit - with the corresponding parameters. - - The initialization shall disable the 603e - core External Exception by calling CoreExtIntDisable( ). - Next, call epicInit( ). Last, enable the 603e core - External Exception by calling CoreExtIntEnable( ). - -4. After EPIC unit has been successfully initialized, - epicIntSourceSet( ) shall be used to register each - external interrupt source. Anytime, an external - interrupt source can be disabled or enabled by - calling corresponding function, epicIntDisable( ), - or epicIntEnable( ). - - Global Timers' resource, base count and frequency, - can be changed by calling epicTmFrequencySet( ) - and epicTmBaseSet( ). - - To stop counting a specific global timer, use - the function, epicTmInhibit while epicTmEnable - can be used to start counting a timer. - -5. To mask a set of external interrupts that are - are certain level below, epicIntPrioritySet( ) - can be used. For example, if the processor's - current task priority register is set to 0x7, - only interrupts of priority 0x8 or higher will - be passed to the processor. - - Be careful when using this function. It may - corrupt the current interrupt pending, selector, - and request registers, resulting an invalid vetor. - - After enabling an interrupt, disable it may also - cause an invalid vector. User may consider using - the spurious vector interrupt service routine to - handle this case. - -6. The EPIC driver routines contains a set - of utilities, Set and Get, for host system - to query and modify the desired EPIC source - registers. - -7. Each external interrupt source shall register - its interrupt service routine. The routine - shall contain all interrupt source specific - processes and keep as short as possible. - - Special customized end of interrupt routine - is optional. If it is needed, it shall contain - the external interrupt source specific end of - interrupt process. - - External interrupt exception vector at 0x500 - shall always call the epicEOI just before - rfi instruction.
