System Real-Time Interrupt Status and Control Register (SRTISC)
This high page register contains status and control bits for the RTI.

Description
7:4
REV[3:0]
Revision Number — The high-order 4 bits of address SDIDH are hard coded to reflect the current mask set
revision number (0–F).
3:0
ID[11:8]
Part Identification Number — Each derivative in the RS08 Family has a unique identification number. The
SC9RS08KA2 Series is hard coded to the value $0800. See also ID bits in Figure 5-4.

RTIF
Real-Time Interrupt Flag — This read-only status bit indicates the periodic wakeup timer has timed out.
0 Periodic wakeup timer not timed out.
1 Periodic wakeup timer timed out.
6
RTIACK
Real-Time Interrupt Acknowledge — This write-only bit is used to acknowledge real-time interrupt request
(write 1 to clear RTIF). Writing 0 has no meaning or effect. Reads always return 0.
5
RTICLKS
Real-Time Interrupt Clock Select — This read/write bit selects the clock source for the real-time interrupt.
0 Real-time interrupt request clock source is internal 1-kHz oscillator.
1 Real-time interrupt request clock source is internal trimmed 32-kHz oscillator (ICS module) and is divided by
32 in RTI logic to produce a trimmed 1-kHz clock source for RTI counter.
