RAPI_UP_COUNT Selects up-count for the count operation.
RAPI_DOWN_COUNT Selects down-count for the count operation.
RAPI_UDF_REGISTER Selects the UDF register for the cause of up/down switching.
RAPI_TAIOUT Selects the input signal at TA
iOUT
pin for the cause of up/down
switching.
RAPI_RISING Selects the rising edge of count source as active edge.
RAPI_FALLING Selects the falling edge of count source as active edge.
RAPI_BOTH Selects both rising and falling edges of count source as active
edges.
• Specifiable definition values when timer A is used (RAPI_TIMER_A0 to RAPI_TIMER_A4
specified)
(Count source) Specify one from { RAPI_EV_EXTERNAL, RAPI_EV_TIMER_AJ,
RAPI_EV_TIMER_AK, RAPI_EV_TIMER_B2 }. The default value is
RAPI_EV_EXTERNAL.
(Operating
states set)
Specify one from { RAPI_TIMER_ON, RAPI_TIMER_OFF }. The default
value is RAPI_TIMER_OFF.
(Pulse output
facility)
Specify one from { RAPI_PULSE_ON, RAPI_PULSE_OFF }. The default
value is RAPI_PULSE_OFF.
(Gate facility) Specify one from { RAPI_GATE_L, RAPI_GATE_H }. If omitted, “No gate
facility” is set.
(Count type) Specify one from { RAPI_AUTO_RELOAD, RAPI_FREE_RUN }. The
default value is RAPI_AUTO_RELOAD.
(Count
direction)
Specify one from { RAPI_UP_COUNT, RAPI_DOWN_COUNT }. The
default value is RAPI_DOWN_COUNT. The count direction can only be set
when the UDF register is used.
(Count direction
switching)
Specify one from { RAPI_UDF_REGISTER, RAPI_TAIOUT }. The default
value is RAPI_UDF_REGISTER.
(Count edge) Specify one from { RAPI_RISING, RAPI_FALLING }. The default value is
RAPI_FALLING.
• Specifiable definition values when timer B is used (RAPI_TIMER_B0 to RAPI_TIMER_B4
specified)
(Count source) Specify one from { RAPI_EV_EXTERNAL, RAPI_EV_TIMER_BJ }. The
default value is RAPI_EV_EXTERNAL.
(Operating
states set)
Specify one from { RAPI_TIMER_ON, RAPI_TIMER_OFF }. The default
value is RAPI_TIMER_OFF.
(Count edge) Specify one from { RAPI_RISING, RAPI_FALLING, RAPI_BOTH }. The
default value is RAPI_FALLING.
[data2]
Specify the interrupt priority level (0–7) to be set in the interrupt control register.
[data3]
Specify the value to be set in the timer register in 16 bits.
