Section 11 8-Bit Timers
11.10
The 8-bit reload timer has the following registers. For details on the module stop control register,
refer to section 22.1.2, Module Stop Control Registers A to D (MSTPCRA to MSTPCRD).
• Timer control register (TCR)
• Timer Counter (TCNT)
• Timer reload register (TLR)
TCNT or TLR can operate as a 16-bit timer using TCNT_4 or TLR_4 (TCNT_6 or TLR_6) as the
upper half and TCNT_5 or TLR_5 (TCNT_7 or TLR_7) as the lower half.
11.10.1 Timer Control Registers 4 to 7 (TCR_4 to TCR_7)
TCR selects the automatic reload function and TCNT clock source, and controls interrupt requests.

Description
Automatic Reload Function Select
Selects the automatic reload function
0: The interval function is selected
1: The automatic reload function is selected
Indicates that TCNT overflows from H'FF to H'00.
0: [Clearing condition]
Read OVF when OVF = 1, then write 0 in OVF
1: [Setting condition]
When TCNT overflows from H'FF to H'00
Timer Overflow Interrupt Enable
Selects whether the OVF interrupt request (OVI) is
enabled or disabled when the OVF flag in TCSR is set to
1.
0: OVF interrupt request (OVI) is disabled
1: OVF interrupt request (OVI) is enabled
Reserved
These bits are always read as 1 and cannot be modified.
