sh implementation

[Suzuki, RyosIII]

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?
