CHAPTER 8 8/16-BIT CAPTURE TIMER/COUNTER

Table 8.4-3 Explanation of Functions of Each Bit in Timer 1 Control Register (TCR1)

	Bit name	Function

		• This bit is set to "1" when the counter value of timer 1 matches the value
		(comparator data latch) set in the timer 1 data register (TDR1).
	TIF1:	• An interrupt request is output when this bit and the interrupt request enable bit
bit7	Compare match	(T1IEN) are "1".
	detection flag bit	Note:
		In the 16-bit mode, the TIF0 bit of TCR0 is valid. The TIF1 bit is unrelated to
		operation.

	TFCR1:	• This bit is used to clear the compare match detection flag bit (TIF1). When this
bit6	Compare match	bit is set to "1", the compare match detection flag is cleared. The flag is not
	detection flag clear bit	affected even if this bit is set to "0".

	T1IEN:	• This bit is used to allow and prohibit interrupt request output to the CPU.
bit5	Interrupt request enable	• An interrupt request is output when this bit and the interrupt request enable bit
	bit	(T0IEN) are "1".

bit4	Not used	• This bit is undefined at read.
bit4	Not used	• At write, this bit does not affect operation.
		• At write, this bit does not affect operation.

		• These bits are used to select the count clocks to be supplied to the counter.
bit3	TCS12, TCS11, TCS10:	• Of seven internal clocks, select one.
bit3	TCS12, TCS11, TCS10:	• When 111B is written to these bits, timer 1 operates as the 16-bit mode.
to	Clock source selection
to	Clock source selection	Note:
bit1	bits	Note:
bit1	bits	In the 16-bit mode, the TCS02, TCS01, and TCS00 bits are valid. The TCS12,

		TCS11, and TCS10 bits are used to select the 16-bit mode only.

		• This bit is used to start and stop the counter.
		• When this bit is set to "1", the counter is cleared and incremented according to
bit0	TSTR1:	the selected count clock. When this bit is set to "0", the counter stops its
bit0	Timer start bit	operation.
	Timer start bit	operation.
		• In the 16-bit mode, only the TSTR0 bit can be used to start the timer. The
		TSTR1 bit is unrelated to operation.

Note:

When using timer 1 in the 16-bit mode, write 111B to the TCS12, TCS11, and TCS10 bits and then control timer 1 with TCR0.
