Register Descriptions
UT Registers
This section gives a brief description of each register bit and its functionality. All algorithms are described in the
main text of the document. The abbreviations after each register indicate if the register is read only (RO), read/write
(R/W), write only (WO), or clear-on-read or clear-on-write (COR/W).
0x indicates a hexadecimal value in the Reset Default column. Otherwise, the entry is binary. This is true for every
register table in the document.
Version Control
Table 54. Register 0x0200: UT Macrocell Version Number (RO)
Reset default of register = 0x0000.
Interrupt
Table 55. Register 0x0201: UT Interrupt (RO)
Reset default of register = 0x0000.
Note: These registers are cleared by accessing registers 0x0202, 0x0203, 0x0204, 0x0205.

Reserved. These bits must be written to their
reset default value (0x00).
UT Macrocell Version Number. The version of
the macrocell will increment each time a
change occurs to the macrocell functionality.
Reserved. These bits must be written to their
reset default value (0x000).
UT Interrupt for Channel D. If this bit is set to
1, it indicates one of the interrupt conditions for
channel D occurred.
UT Interrupt for Channel C. If this bit is set to
1, it indicates one of the interrupt conditions for
channel C occurred.
UT Interrupt for Channel B. If this bit is set to
1, it indicates one of the interrupt conditions for
channel B occurred.
UT Interrupt for Channel A. If this bit is set to
1, it indicates one of the interrupt conditions for
channel A occurred.
