TIMING SYSTEM
TECHNICAL DATA
9-17
9.6.1 Pulse Accumulator Control Register
Four of this register's bits control an 8-bit pulse accumulator system. Another bit en-
ables either the OC5 function or the IC4 function, while two other bits select the rate
for the real-time interrupt system.
DDRA7 — Data Direction Control for Port A Bit 7
The pulse accumulator uses port A bit 7 as the PAI input, but the pin can also be used
as general-purpose I/O or as an output compare. Note that even when port A bit 7 is
configured as an output, the pin still drives the input to the pulse accumulator. Refer to
SECTION 6 PARALLEL I/O
for more information.
PAEN — Pulse Accumulator System Enable
0 = Pulse accumulator disabled
1 = Pulse accumulator enabled
PAMOD — Pulse Accumulator Mode
0 = Event counter
1 = Gated time accumulation
PEDGE — Pulse Accumulator Edge Control
This bit has different meanings depending on the state of the PAMOD bit, as shown in
the following table:
DDRA3 — Data Direction Register for Port A Bit 3
Refer to
SECTION 6 PARALLEL I/O
.
I4/O5 — Input Capture 4/Output Compare 5
Refer to
9.2 Input Capture
.
RTR[1:0] — RTI Interrupt Rate Selects
Refer to
9.4 Real-Time Interrupt
.
9.6.2 Pulse Accumulator Count Register
This 8-bit read/write register contains the count of external input events at the PAI in-
put, or the accumulated count. The counter is not affected by reset and can be read or
written at any time. Counting is synchronized to the internal PH2 clock so that incre-
menting and reading occur during opposite half cycles.
