615 / 1158 page  Section 10 16-Bit Timer Pulse Unit (TPU) Rev.1.00 Jun. 07, 2006 Page 563 of 1102 REJ09B0294-0100 10.5 Interrupt Sources There are three kinds of TPU interrupt sources: TGR input capture/compare match, TCNT overflow, and TCNT underflow. Each interrupt source has its own status flag and enable/disable bit, allowing generation of interrupt request signals to be enabled or disabled individually. When an interrupt request is generated, the corresponding status flag in TSR is set to 1. If the corresponding enable/disable bit in TIER is set to 1 at this time, an interrupt is requested. The interrupt request is cleared by clearing the status flag to 0. Relative channel priority levels can be changed by the interrupt controller, but the priority within a channel is fixed. For details, see section 5, Interrupt Controller. Table 10.37 lists the TPU interrupt sources.
