CHAPTER 12 16-BIT RELOAD TIMER
Table 12.4-2 Timer Control Status Register (TMCSRL0/TMCSRL1)
Bit name
Function
bit6
OUTE:
Timer output enable bit
•
This bit enables or disables output from the timer output pin.
•
When this bit is "0", the pin functions as a general-purpose port. When this bit is
"1", the pin functions as a timer output pin.
•
In reload mode, the output waveform of this timer output pin
toggles. In single-shot mode, the timer outputs a rectangular
waveform that indicates that counting is in progress is output.
bit5
OUTL:
Pin output level
selection bit
•
This register is used to select the output level of the timer output pin.
•
The output level of the pin is inverted depending on whether this bit is "0" or "1".
bit4
RELD:
Reload selection bit
•
This bit enables reloading.
•
When this bit is "1", the timer is in reload mode. At the same time an underflow
occurs, the contents of the reload register are loaded into the counter, and counting
continues.
•
When this bit is "0", the timer is in single-shot mode. Counting stops when an
underflow occurs.
bit3
INTE:
Interrupt request
enable bit
•
This bit enables or disables underflow interrupt request to the CPU.
•
When this bit and the underflow interrupt request flag (UF) bit are "1", the timer
outputs an interrupt request.
bit2
UF:
Underflow interrupt
request flag bit
•
This bit is set to "1" when a counter underflow occurs.
•
Writing "0" to this bit clears it. Writing "1" to this bit does not change the bit value
and has no effect on other bits.
•
This bit is also cleared when EI
2
OS is activated.
bit1
CNTE:
Count enable bit
•
The bit enables or disables counting.
•
When this bit is set to "1", the counter is placed in trigger standby mode. When a
trigger occurs, actual counting starts.
bit0
TRG:
Software trigger bit
•
This bit starts the interval timer function or counter function with software.
•
Writing "1" to this bit applies a software trigger, causing the contents of the reload
register to be loaded into the counter and starting counter operation. Writing "0" to
this bit has no effect.
•
Trigger input from this trigger is always valid when the CNTE bit is set to "1"
regardless of the operating mode.
