PAMOD — Pulse Accumulator Mode
0 = External event counting
1 = Gated time accumulation
PEDGE — Pulse Accumulator Edge Control
This bit has different meanings depending on the state of the PAMOD bit.
Bits 3-2 — Not Implemented
These bits always read zero.
RTR1 and RTR0 — RTI Interrupt Rate Selects
These two bits select one of four rates for the real time periodic interrupt circuit (see
Table 8-1
). Reset clears these two bits and after reset, a full RTI period elapses before
the first RTI interrupt.
