ID[11:0] — Part Identification Number
5.8.6
This register contains one read-only status flag, one write-only acknowledge bit, three read/write delay
selects, and three unimplemented bits, which always read 0.
RTIF — Real-Time Interrupt Flag
RTIACK — Real-Time Interrupt Acknowledge
RTICLKS — Real-Time Interrupt Clock Select
RTIE — Real-Time Interrupt Enable
RTIS2:RTIS1:RTIS0 — Real-Time Interrupt Period Selects
Freescale Semiconductor
Each derivative in the HCS08 Family has a unique identification number. The MC9S08GB/GT is hard
coded to the value $002.
This read-only status bit indicates the periodic wakeup timer has timed out.
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.
This read/write bit selects the clock source for the real-time interrupt.
This read-write bit enables real-time interrupts.
These read/write bits select the wakeup period for the RTI. The clock source for the real-time interrupt
is its own clock source, which oscillates with a period of approximately 1/f
other MCU clock sources. Using an external clock source, the delays will be crystal frequency divided
by value in RTIS2:RTIS1:RTIS0.
1 = Periodic wakeup timer timed out.
0 = Periodic wakeup timer not timed out.
1 = Real-time interrupt request clock source is external clock.
0 = Real-time interrupt request clock source is internal oscillator.
1 = Real-time interrupts enabled.
0 = Real-time interrupts disabled.
