Register 6: Masked Interrupt Status and Clear (MISC), offset 0x058
On a read, this register gives the current masked status value of the corresponding interrupt. All of
the bits are R/W1C and this action also clears the corresponding raw interrupt bit in the RIS register
(see page 192).

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
MOSC Power Up Masked Interrupt Status
This bit is set when the TMOSCPUP timer asserts. The interrupt is cleared
by writing a 1 to this bit.
USB PLL Lock Masked Interrupt Status
This bit is set when the USB PLL TUSBREADY timer asserts. The interrupt
is cleared by writing a 1 to this bit.
PLL Lock Masked Interrupt Status
This bit is set when the PLL TREADY timer asserts. The interrupt is cleared
by writing a 1 to this bit.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
BOR Masked Interrupt Status
The BORMIS is simply the BORRIS ANDed with the mask value, BORIM.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
