COPE — COP Enable
This bit is readable any time. COPE, CM1, and CM0 together may be
written with a single write, only once, after reset. This bit is cleared by
reset.
1 = COP enabled
0 = COP disabled
CM1 — COP Mode Bit 1
Used in conjunction with CM0 to establish the COP timeout period,
this bit is readable any time. COPE, CM1, and CM0 together may be
written with a single write, only once, after reset. This bit is cleared by
reset. See Table 5-1 for timeout period options.
CM0 — COP Mode Bit 0
Used in conjunction with CM1 to establish the COP timeout period,
this bit is readable any time. COPE, CM1, and CM0 together may be
written with a single write, only once, after reset. This bit is cleared by
reset. See Table 5-1 for timeout period options.
Bits 7–5 — Not Used
These bits always read as zero.
