SMR2 Register Events
The SMR2 register function is similar to the standard SMR feature used in previous Z8
CPU-compatible parts. Register bits SMR2[4:2] are set to select one of seven event
modes, as displayed in
the state of SMR2[6]; when they are the same, a SMR event is generated. If
SMR2[4:2]=000, no event source is selected by SMR2.
The logic configured by the SMR2 register ignores any port pins that are configured as an
output, or that are selected as source pins in registers SMR1 or SMR3.
The SMR2 register is summarized in

The SMR2 register logic ignores any pin configured
as an output in the P2M or P3M registers or
as a source in the SMR1 or SMR3 registers.
