M3727GM6/M8–XXXSP/FP M37272E8SP/FP
Ports P1, P2, P30, P31
Direction register
Data bus
Port latch
CMOS output
Ports P1, P2, P30, P31
Notes 1: Each port is also used as follows :
P10 : OUT2
P20 : SCLK
P11 : SCL1
P21 : SOUT
P12 : SCL2
P22 : SIN
P13 : SDA15
P23 : TIM3
P14 : SDA2
P24 : TIM2
P15 : AD1/INT3
P30 : AD5
P16 : AD2
P31 : AD6
P17 : AD3
2: The output structure of ports P30 and P31 can be selected either CMOS output or N-channel open-
drain output structure (when selecting N-channel open-drain, it is the same with P00–P07).
3: The output structure of ports P11–P14 is N-channel open-drain output when using as multi-master
I²C-BUS interface (when selecting N-channel open-drain, it is the same with P00–P07).
4: The output structure of ports P20 and P21 is N-channel open-drain output when using as serial
output (when selecting N-channel open-drain, it is the same with P00–P07).
