RSDS Port Definition
The RSDS terminal is one pair of 2 ports, and a differential signal is output. The terminals have external
terminal names and a POF definition names corresponding to each other.
The relations are shown and specified as followings.
Configure POF=2 in corresponding PPC_PCFGR to use RSDS, and the pair of RSDS ports will
become effective without any configuration to GFXCORE_RSDS_INACTIVE.
On the other hand, if you only write POF=2 for GFXCORE_RSDS_INACTIVE, the pair of RSDS ports
will not become effective, and to be an input status port.

HyperBus Interface Port Configuration
HyperBus Interface ch.0 and ch.1 are assigned to the same GPIO, the channel must be selected either
ch.0 or ch.1 in addition to POF register settings. General Purpose Output
Register(HYPERBUSIn_GPOR) in HyperBus Interface ch.0 is used for configuration of channel selection.
The bit and function for channel selection are the followings.
GPO[0] Description
0 Select HyperBus Interface ch.0
1 Select HyperBus Interface ch.1
Note:
−
GPO[1] in HYPERBUSIn_GPOR of HyperBus Interface ch.0 is not used.
−
GPO[1:0] in HYPERBUSIn_GPOR of HyperBus Interface ch.1, ch.2 are not used.
−
If HyperBus Interface ch.2 is used, the configuration of GPO bit is unnecessary.
