[bit 13] EDIR (End interrupt request)
This flag indicates when counting ends in pulse width count mode. A count end interrupt request is
generated if the interrupt is enabled (bit 12: EDIE = "1") when this bit is set.
Set timing
Clear timing
Note: This bit has no meaning in timer mode.
After a reset: Initialized to "0".
Read-only. Writing to the bit does not change the value.
[bit 12] EDIE (End interrupt enable)
Controls the count end interrupt request in pulse width count mode as follows.
0
1
Note: Always set to "0" during timer mode.
After a reset: Initialized to "0".
Readable and writable.
[bit 11] OVIR (Overflow interrupt request)
This flag indicates when the 16-bit up-count timer overflows from FFFF
modes. A timer overflow interrupt request is generated if the interrupt is enabled (bit 10: OVIE = "1")
when this bit is set.
Set timing
Clear timing
After a reset: Initialized to "0".
Readable and writable. However, only writing "0" is valid. Writing "1" does not change the bit value.
Read-modify-write instructions always read the bit as "1" regardless of the actual bit value.
[bit 10] OVIE (Overflow interrupt enable)
Controls the timer overflow interrupt request as follows.
0
1
After a reset: Initialized to "0".
Readable and writable.
MB90580 Series
Set when pulse width counting ends (when the count result is placed in PWCR).
Cleared by reading PWCR (the count result).
Disable output of count end interrupt requests
(do not generate an interrupt when EDIR is set).
Enable output of count end interrupt requests (generate an interrupt when EDIR is set).
Set when a timer overflow occurs (FFFF
Cleared by writing "0" or by the extended intelligent I/O service.
Disable output of overflow interrupt requests
(do not generate an interrupt when OVIR is set).
Enable output of overflow interrupt requests
(generate an interrupt when OVIR is set).
