Description
Module Stop 10
When the MSTP10 bit is set to 1, the supply of the
clock to the H-UDI is halted.
0: H-UDI runs
1: Clock supply to H-UDI halted
Module Stop 9
When the MSTP9 bit is set to 1, the supply of the
clock to the UBC is halted.
0: UBC runs
1: Clock supply to UBC halted
Module Stop 8
When the MSTP8 bit is set to 1, the supply of the
clock to the DMAC is halted.
0: DMAC runs
1: Clock supply to DMAC halted
Module Stop 7
When the MSTP7 bit is set to 1, the supply of the
clock to the DSP is halted.
0: DSP runs
1: Clock supply to DSP halted
Reserved
This bit is always read as 0. The write value should
always be 0. If 1 is written to this bit, correct
operation cannot be guaranteed.
Module Stop 5
When the MSTP5 bit is set to 1, the supply of the
clock to the cache memory is halted.
0: The cache memory runs
1: Clock supply to the cache memory halted
