ST20–SWC
interface of the ST20450. This code is either downloaded from the host using the hardware serial link
using the host server or is incorporated into a ROM using the EPROM programming tool.
For an ST20 variant with a memory interface different from the ST20450, example bootstrap code
is provided.
2.3.9 Interrupt and trap handling
Library support is supplied for trap handlers and ST20450 interrupt handlers. This allows trap
handlers and ST20450 interrupt handlers to be written in C which will use the on-chip trap handling
and interrupt handling support. Interrupt handlers for other ST20 variants may be based on the
provided libraries.
