Description
Read/Write set. All field bits are readable and writable. After reset, register field is set to a non-zero
value specified in the text.
Self-Clear. Writing a one to this register causes the desired function to be immediately executed, then
the register field is automatically cleared to zero when the function is complete.
Value written to the register field doesn’t take effect until soft reset is executed.
Write only. Reads to this type of register field return undefined data.
For all binary equations appearing in the register map, the symbol | is equal to a binary
OR operation.
