tionality replaces TM1000 functions.
The hardware reset value of EVO_CTL register is
0x10000000, which means that EVO functions are dis-
abled on reset and must be enabled by software. The MS
four bits indicate the EVO revision number.
To ensure compatibility with future devices, any unde-
fined MMIO bits should be ignored when read, and writ-
ten as ‘0’s.
