Field Description

RTIF
RTIF – Real-Time Interrupt Flag
The RTIF bit indicates the real-time interrupt request status when configured for Run or Stop4 modes.
0 = Real-time interrupt request is not pending; Result of power-on reset and exit of Stop1; Existing state
retained from resets of low voltage detection, external pin, COP, PWU, illegal opcode, illegal address, soft
reset, and background debugger.
1 = Real-time interrupt request is pending.
6
RTIACK
RTIACK – Real-Time Interrupt Acknowledge
Writing a logic 1 to RTIACK clears the real-time interrupt request and clears RTIF to a logic 0.
0 = Read result; Write no effect; Result of Reset
1 = Write 1 to clear RTIF for Real-time interrupt acknowledge.
5
RTICLKS
RTICLKS – Real-Time Interrupt Clock Select
The RTICLKS bit selects the clock source for the real-time interrupt request.
0 = Real-time interrupt request clock source is internal oscillator; Result of Reset and exit of Stop1.
1 = Real-time interrupt request clock source is external clock.
4
RTIE
RTIE – Real-Time Interrupt Enable
The RTIE bit enables the interrupt output of the RTI module from Run or Stop4 modes.
0 = Real-time interrupt request disabled; Result of Reset and exit of Stop1.
1 = Real-time interrupt request enabled.
2:0
RTIS[2:0]
RTIS[2:0] – The 3 bits RTIS[2:0] selects the real-time interrupt period derived from the selected real-time
interrupt clock source.
0 0 0 = Off; Result of Reset and exit of Stop1.
0 0 1 = 2 ms
0 1 0 = 4 ms
0 1 1 = 8 ms
1 0 0 = 16 ms
1 0 1 = 32 ms
1 1 0 = 64 ms
1 1 1 = 128 ms
10.23.3.2 PMC status and control 1 register (SPMSC1)
PMCSC1 contains the status and control bits associated with the PMC Voltage Regulator
(VREG) and Low Voltage Detect (LVD) functions.
