8-3-2 Setup Example

„Timer Operation Setup (Timer 6)

Timer 6 generates an interrupt constantly for timer function. Fs(fosc = 20 MHz) is selected as a clock source to generate an interrupt every 250 cycles (25 µs).

An example setup procedure, with a description of each step is shown below.

	Setup Procedure					Description
(1)	Enable the binary counter			(1)	Set the TM6LRS flag of the timer 6 mode
	initialization.				register (TM6MD) to "0". At that time, the
	TM6MD (x'3F6A')				initialization of the timer 6 binary counter
	bp7	: TM6CLRS = 0			(TM6BC) is enabled.
(2)	Select the clock source.			(2)	Clock source can be selected by the TM6CK3-1
	TM6MD (x'3F6A')				flag of the TM6MD register. Actually, fs is
	bp3-1	: TM6CK3-1 = 001			selected.
(3)	Set the interrupt generation cycle.			(3)	Set the interrupt generation cycle to the timer
	TM6OC (X'3F69')		= x'F9'		6 compare register (TM6OC). At that timer,
					TM6BC is initialized to x'00'.
(4)	Enable the interrupt request			(4)	Set the TM6CLRS flag of the TM6MD register to
	generation.				"1" to enable the interrupt request generation.
	TM6MD (x'3F6A')
	bp7	: TM6CLRS = 1
(5)	Set the interrupt level.			(5)	Set the interrupt level by the TM6LV1-0 flag of
	TM6ICR (x'3FEF')				the timer 6 interrupt control register (TM6ICR).
	bp7-6	: TM6LV1-0 = 01			If the interrupt request flag may be already set,
					clear them.
(6)	Enable the interrupt.				[	Chapter 3 3-1-4. Interrupt Flag Setup ]
	TM6ICR (x'3FEF')
	bp1	: TM6IE	= 1	(6)	Set the TM6IE flag of the TM6ICR register to "1"
					to enable the interrupt.

* the above steps (1), (2) can be set at once.

As TM6OC is set, TM6BC is initialized to x'00' to count up.

When TM6BC matches TM6OC, the timer 6 interrupt request flag is set to "1" at the next count clock and TM6BC is cleared to x'00' to restart counting.
