- Subject: sh implementation
Hello all,
I have a question about HAL_RESET_CLOCK and HAL_INTERRUPT_
ACKNOWREDGE in sh implementation.
it seems sh's HAL_RESET_CLOCK clears interrupt cause. and
HAL_INTERRUPT_ACKNOWREDGE does nothing. but in other
architectures, mips, arm, sparc, i386 ... I see
HAL_RESET_CLOCK is used to reset clock counter not to clear
interrupt cause. HAL_INTERRUPT_ACKNOWREDGE is used to clear
interrupt cause.
I feel that sh implementation is different from others.
why?
