• Increment
• When the 8-bit counter content matches with the TREMIN register
• 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
Write 1 (count starts) to the TSTART bit in the TRECR1 register
Write 0 (count stops) 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 followings:
• Programmable I/O ports
• Output any one of f2, f4 and 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 the TSTART and TCSTF bits 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
content, the value returns to 00h and count continues.
The count value is held while count stops.
Every time the 8-bit counter value matches with the TREMIN register
value, TREO output polarity is reversed. The TREO pin outputs “L”
after reset is deasserted and the Timer RE reset by the TRERST bit
in the TRECR1 register. Output level is held by setting the TSTART
bit to 0 (count stops).
