Port 9
Pin configuration in master mode,
or in slave mode when STAC bit is 0
P9₁/IRQ₁/EIOW^*2
P9₁ (input/output)/IRQ₁ (input)
P9₀/IRQ₂/ADTRG/ECS₂^*2 P9₀ (input/output)/IRQ₂ (input)/ADTRG (input)
Pin configuration in slave mode
when STAC bit is 1
IRQ₁ (input)/EIOW ^*2 (input)
IRQ₂ (input)/ECS₂^*2 (input)
Note: *2 The EIOW and ECS₂ pin functions apply to the H8/3337 Series only. The H8/3397 Series
does not support a host interface, and therefore does not have these pin functions.
