Notes: 1. When the IIC2/SSU is used as the IIC2 function, the SCL and SDA functions can be
allocated to the P56 and P57 pins only because SCL and SDA require buffers
dedicated for IIC input/output. The PMC can not be used to allocate the SCL and SDA
functions to other pins. When the IIC2/SSU is used for the SSU function except *
2
, there
is no restriction.
The P56 and P57 pins have different characteristics from other pins. When these pins
are used as the SCL and SDA pins for the IIC2, they provide NMOS open drain output.
When the P56 and P57 pins are used for other output functions, they provide NMOS
push-pull output and characteristics of the high level output is different from that of the
CMOS output.
2. If the NMOS open-drain output is selected for the SCS output pin, use the PMC to
allocate that pin from port 5
