0 0 0
b Bit Name
0, 1 No function assigned. Fix to "0".
2 TOPIS9 (TOP9 interrupt request status bit)
3 TOPIS8 (TOP8 interrupt request status bit)
4, 5 No function assigned. Fix to "0".
6 TOPIM9 (TOP9 interrupt request mask bit)
7 TOPIM8 (TOP8 interrupt request mask bit)
Note 1: Only writing "0" is effective. Writing "1" has no effect; the bit retains the value it had before the write.
Note: • TOP10 has only one interrupt source in the interrupt group, so that its status and mask registers are nonexistent in the MJT
interrupt control registers. (They are controlled directly by the Interrupt Controller.)
