CHAPTER 5 TIME-BASE TIMER

Table 5.3-1 Explanation of Functions of Each Bit in Time-base Timer Control Register (TBTC)

	Bit name	Description

		• This bit is set to "1" when the specified bit of the time-base timer counter
	TBOF:	overflows.
	TBOF:	• An interrupt request is sent when this bit and the interrupt request enable bit
bit7	Overflow interrupt request
bit7	Overflow interrupt request	(TBIE) are both "1".
	flag bit	(TBIE) are both "1".
	flag bit	• While this bit is written, it is cleared when "0" is specified, and nothing is

		changed and affected when "1" is specified.

	TBIE:	This bit enables or disables an interrupt request to be output to the CPU. An
bit6	TBIE:	interrupt request is output when this bit and the overflow interrupt request flag bit
bit6	Interrupt request enable bit
	Interrupt request enable bit	(TBOF) are both "1".
		(TBOF) are both "1".

bit5		• These bits are undefined when they are read.
to	Unused bits	• These bits are undefined when they are read.
to	Unused bits	• Nothing is affected when they are written.
bit3		• Nothing is affected when they are written.
bit3

bit2,	TBC1, TBC0:	• These bits specify a time interval for the interval timer.
bit2,	TBC1, TBC0:	• The interval timer bits of the time-base timer counter are specified.
bit1	Time interval selection bits
bit1	Time interval selection bits	• One of four time intervals can be selected.
		• One of four time intervals can be selected.

		• This bit clears the time-base timer counter.
	TBR:	• The counter is cleared to 000000H when "0" is written to this bit, nothing is
bit0	Time-base timer	changed and affected when "1" is written.
	initialization bit	Note:
		This bit is always "1" at the beginning of reading.
