|
51 |
|
|
// Description: The macros defined here provide the HAL APIs for handling

// interrupts and the clock for AM33 variants of the MN10300
|
53 |
|
|
// architecture.

|
// The MN10300 has a somewhat complex interrupt structure. Besides the
|
73 |
|
|
// reset and NMI vectors there are seven maskable interrupt vectors
|
74 |
|
|
// which must point to code in the 64k starting at 0x40000000. There
|
75 |
|
|
// are also 25 Interrupt control groups, each of which can have 4
|
76 |
|
|
// interrupt lines attached, for a theoretical total of 100 interrupts
|
77 |
|
|
// (!). Some of these are dedicated to specific devices, other to
|
78 |
|
|
// external pins, and others are not connected to anything, resulting
|
79 |
|
|
// in only 45 that can actually be delivered. Each control group may
|
80 |
|
|
// be assigned one of seven interrupt levels, and is delivered to the
|
81 |
|
|
// corresponding vector. Software can then use a register to determine
|
82 |
|
|
// the delivering group and detect from there which interrupt has been
|
83 |
|
|
// delivered.
|
84 |
|
|
//
|
85 |
|
|
// The approach we will adopt at present is for the code attached to
|
86 |
|
|
// each vector to save state and jump via a table to a VSR. The
|
87 |
|
|
// default VSR will fully decode the delivered interrupt into a table
|
88 |
|
|
// of isr/data/object entries. VSR replacement will operate on the
|
89 |
|
|
// first level indirection table rather than the hardware
|
90 |
|
|
// vectors. This is the fastest mechanism, however it needs 100*3*4 +
|
91 |
|
|
// 7*4 = 1228 bytes for the tables.
