f4, f8, f32, fC4
• Increment
• When the 8-bit counter content matches with the TREMIN register content,
• When RCS2 = 0 (4-bit counter is not used)
• When RCS2 = 1 (4-bit counter is used)
fi: Frequency of count source
n: Setting value of TREMIN register
1 (count starts) is written to the TSTART bit in the TRECR1 register
0 (count stops) is written to the TSTART bit in the TRECR1 register
When the 8-bit counter content matches with the TREMIN register content
Select any one of the following:
• Programmable I/O ports
• Output f2, f4, or f8
• Compare output
When reading the TRESEC register, the 8-bit counter value can be read.
When reading the TREMIN register, the compare value can be read.
Writing to the TRESEC register is disabled.
When bits TSTART and TCSTF in the TRECR1 register are set to 0 (timer
stops), writing to the TREMIN register is enabled.
• Select use of 4-bit counter
• Compare output function
the value returns to 00h and count continues. The count value is held while
count stops.
1/fi x 2 x (n+1)
1/fi x 32 x (n+1)
Every time the 8-bit counter value matches the TREMIN register value,
TREO output polarity is reversed. The TREO pin outputs “L” after reset is
deasserted and the timer RE is reset by the TRERST bit in the TRECR1
register. Output level is held by setting the TSTART bit to 0 (count stops).
