Advance Information
322
The following TIMB sources can generate interrupt requests:
The WAIT and STOP instructions put the MCU in low power-
consumption standby modes.
The TIMB remains active after the execution of a WAIT instruction. In
wait mode, the TIMB registers are not accessible by the CPU. Any
enabled CPU interrupt request from the TIMB can bring the MCU out of
wait mode.
If TIMB functions are not required during wait mode, reduce power
consumption by stopping the TIMB before executing the WAIT
instruction.
The TIMB is inactive after the execution of a STOP instruction. The
STOP instruction does not affect register conditions or the state of the
TIMB counter. TIMB operation resumes when the MCU exits stop mode.

For More Information On This Product,
TIMB overflow flag (TOF) — The TOF bit is set when the TIMB
counter value rolls over to $0000 after matching the value in the
TIMB counter modulo registers. The TIMB overflow interrupt
enable bit, TOIE, enables TIMB overflow CPU interrupt requests.
TOF and TOIE are in the TIMB status and control register.
TIMB channel flags (CH1F–CH0F) — The CHxF bit is set when an
input capture or output compare occurs on channel x. Channel x
TIMB CPU interrupt requests are controlled by the channel x
interrupt enable bit, CHxIE.
