-CONTENT:
-
- epic.h
- epic1.c
- epic2.s
-
-WHAT ARE THESE FILES:
-
-These files contain MPC8240 (Kahlua) EPIC
-driver routines. 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. Refer to the routine,
- epic_exception, for a code sample.
