CM
Compatibility Mode allows the XA to execute most translated 80C51 code on the XA. The
XA register file must copy the 80C51 mapping to data memory and mimic the 80C51
indirect addressing scheme.
PZ
Page Zero mode forces all program and data addresses to 16-bits only. This saves stack
space and speeds up execution but limits memory access to 64k.

GATE
Gating control when set. Timer/Counter "n" is enabled only while "INTn" pin is high and "TRn"
control bit is set. When cleared Timer "n" is enabled whenever "TRn" control bit is set.
C/T
Timer or Counter Selector cleared for Timer operation (input from internal system clock.) Set for
Counter operation (input from "Tn" input pin).
