19.4.5
The channel interrupt enable register (CIER) allows the CPU to enable or disable the ability of individual
TPU3 channels to request interrupt service. Setting the appropriate bit in the register enables a channel to
make an interrupt service request; clearing a bit disables the interrupt.
19.4.6
Encoded 4-bit fields within the channel function select registers specify one of 16 time functions to be
executed on the corresponding channel. Encodings for predefined functions are found in

Channel interrupt request level. This three-bit field specifies the interrupt request level for all
channels. This field is used in conjunction with the ILBS field to determine the request level of
TPU3 interrupts.
Interrupt level byte select. This field and the CIRL field determine the level of TPU3 interrupt
requests.
