Description
FIELDNAME
Depending on its placement in the read or write row, indicates that the bit is not readable or not
writable
Identifies the field. Its presence in the read or write row indicates that it can be read or written.
Register field types
R
Read only. Writing this bit has no effect
W
Write only
R/W
Standard read/write bit. Only software can change the bit’s value (other than a hardware reset).
rwm
A read/write bit that can be modified by hardware in some fashion other than by a reset
w1c
Write one to clear. A status bit that can be read, and is cleared by writing a one.
Self-clearing bit Writing a one has some effect on the module, but it always reads as zero. (Previously designated
slfclr)
S
Set: Pattern on the data bus is ORed with and written into the register.
C
Clear: Pattern on the data bus is a mask. If a bit on the mask is set, then the corresponding
register bit is cleared.
Reset values
0
Resets to zero
