(d) Count value hold operation
(e) Counter read operation during count operation
(f) Underflow operation
(g) Interrupt operation
• INTTT0CC1 interrupt:
• INTTT0OV interrupt:
• INTTT0EC interrupt:
The value of the 16-bit counter is held by the TT0CTL2.TT0ECC bit in the encoder compare mode. The value
of the 16-bit counter is reset to FFFFH when the TT0ECC bit = 0 and TT0CTL0.TT0CE bit = 0. When the
TT0CE bit is next set to 1, the set value of the TT0TCW register is transferred to the 16-bit counter and a count
operation is performed.
If the TT0ECC bit = 1 and TT0CE bit = 0, the value of the 16-bit counter is held. When the TT0CE bit is next
set to 1, the counter resumes the count operation from the held value.
The value of the 16-bit counter of TMT0 can be read by using the TT0CNT register during the count operation.
When the TT0CTL0.TT0CE bit = 1, the value of the 16-bit counter can be read by reading the TT0CNT register.
If the TT0CNT register is read when the TT0CTL2.TT0ECC bit = 0 and TT0CE bit = 0, however, it is 0000H.
The held value of the TT0CNT register is read if the register is read when the TT0ECC bit = 1 and TT0CE bit =
0.
A 16-bit counter underflow occurs at the timing when the 16-bit counter value changes from 0000H to FFFFH
in the encoder compare mode. When an underflow occurs, the TT0OPT1.TT0EUF bit is set to 1 and an
interrupt request signal (INTTT0OV) is generated.
TMT0 generates the following four types of interrupt request signals.
• INTTT0CC0 interrupt:
This signal functions as a match interrupt request signal of the CCR0 buffer register
and as a capture interrupt request signal to the TT0CCR0 register.
This signal functions as a match interrupt request signal of the CCR1 buffer register
and as a capture interrupt request signal to the TT0CCR1 register.
This signal functions as an overflow interrupt request signal.
This signal functions as a valid edge detection interrupt request signal of the
encoder clear input (TECR0 pin).
