RESET:
The channel interrupt status register (CISR) contains one interrupt status flag per
channel. Time functions specify via microcode when an interrupt flag is set. Setting a
flag causes the TPU3 to make an interrupt service request if the corresponding CIER
bit is set. To clear a status flag, read CISR, then write a zero to the appropriate bit.
CISR is the only TPU3 register that can be accessed on a byte basis.
