PAMOD — Pulse Accumulator Mode
0 = External event counting
1 = Gated time accumulation
PEDGE — Pulse Accumulator Edge Control
The effects of PEDGE and PAMOD are shown in the following table.
PCLKS — PCLK Pin State (Read Only)
I4/O5 — Input Capture 4/Output Compare 5
0 = Output compare 5 enabled
1 = Input capture 4 enabled
PACLK[1:0] — Pulse Accumulator Clock Select (Gated Mode)
PACNT — Pulse Accumulator Counter
8-bit read/write counter used for external event counting or gated time accumulation.
TIC[1:3] — Input Capture Registers 1–3
$YFF90E, $YFF910, $YFF912
The input capture registers are 16-bit read-only registers which are used to latch the value of TCNT
when a specified transition is detected on the corresponding input capture pin. They are reset to $FFFF.
TOC[1:4] — Output Compare Registers 1–4
$YFF914, $YFF916, $YFF918, $YFF91A
The output compare registers are 16-bit read/write registers which can be used as output waveform
controls or as elapsed time indicators. For output compare functions, they are written to a desired match
value and compared against TCNT to control specified pin actions. They are reset to $FFFF.
TI4/O5 — Input Capture 4/Output Compare 5 Register
$YFF91C
This register serves either as input capture register 4 or output compare register 5, depending on the
state of I4/O5 in PACTL.
TCTL1 determines output compare mode and output logic level. TCTL2 determines the type of input
capture to be performed.
