Requests to this port

- pavr_s5_alu_sregwr_rq
This signalizes that an instruction that uses the ALU wants to update the arithmetic flags.
Flags I (general interrupt enable, SREG(7)) and T (transfer bit, SREG(6)) are left unchanged.
- pavr_s5_setiflag_sregwr_rq
This sets the I flag.
Only RETI instruction needs this. - pavr_s5_clriflag_sregwr_rq
This clears the I flag.
No instruction explicitely requests this.
This is only requested when an interrupt is acknowledged (during the consequent implicit CALL).
