Write to timer
Selectable function
1. Wait for one or more count source cycles to write after the count starts.
2. Any operation can be selected for timer A3. Timer A2 is used only for the normal processing operation. Timer
A4 is used only for the multiply-by-4 operation.

Timers A2, A3, and A4

Two-phase pulse input
Two-phase pulse signals applied to pins TAiIN and TAiOUT (i = 2 to 4)
• Count direction (increment or decrement) is set by a two-phase pulse signal.
• Reload/Free-run type can be selected.
(FFFFh - n + 1): when incrementing
n + 1: for decrementing
The TAiS bit in the TABSR Register is set to 1 (count starts)
The TAiS bit is set to 0 (count stops)
Two-phase pulse input
A read from the TAi register returns a counter value
• A write to the TAi register while the count is stopped:
• A write to the TAi register while counting:
• Normal processing operation (Timers A2 and A3)
• Multiply-by-4 processing operation (Timers A3 and A4)
• Counter reset by a Z-phase pulse signal input (Timer A3)
n: setting value of the TAi register, 0000h to FFFFh
Reload function: The contents of the reload register are reloaded into the
counter and the count continues when the timer underflows or overflows.
Free-running function: The counter continues running without reloading when
the timer underflows or overflows.
The value is written to both the reload register and the counter.
The value is written to the reload register (It is transferred to the counter at the
next reload timing).
While a high-level (“H”) signal is applied to the TAjOUT pin (j = 2, 3), the timer
increments a counter value at the rising edge of the TAjIN pin or decrements a
counter value at the falling edge.
The timer increments the counter value in the following timings:
-at the rising edge of TAkIN while TAkOUT is “H” (k = 3, 4)
-at the falling edge of TAkIN while TAkOUT is “L”
-at the rising edge of TAkOUT while TAkIN is “L”
-at the falling edge of TAkOUT while TAkIN is “H”
The timer decrements the counter in the following timings:
-at the rising edge of TAkIN while TAkOUT is “L”
-at the falling edge of TAkIN while TAkOUT is “H”
-at the rising edge of TAkOUT while TAkIN is “H”
-at the falling edge of TAkOUT while TAkIN is “L”
The counter value is cleared to 0 by a Z-phase pulse signal input
