Pin configuration in slave mode when STAC bit is 0
P8₆ (input/output)/IRQ₅ (input)/SCK₁ (input/output)/SCL ^*1
IRQ₄ (input)/CS₂ (input)^*2
IRQ₃ (input)/IOW (input) ^*2
IOR (input)^*2

P8₁ (input/output)/GA₂₀ (output)^*2
HA₀ (input)^*2
Notes: *1 The SCL pin function applies to the H8/3337 Series only. The H8/3397 Series does
not support an I²C bus interface, and therefore has no SCL pin function.
*2 The CS₂, IOW, IOR, CS₁, GA₂₀, and HA₀ pin functions apply to the H8/3337 Series
only. The H8/3397 Series does not support a host interface, and theref ore does not
have these pin functions.
