Description
Peripheral A : CTS2 UART #2 Clear to Send Signal
1 PA5 J10_1 J4_2
Peripheral B : MCBD1
Disabled.
Data Flash connected with SPI0 is used for Eddy-CPU v2.1/v2.5. For
this reason SPI0 and MCDB0, MCDB3, and MCCDB signals,
multiplexing, cannot be used, thus Multimedia Card Slot B is disabled.
Peripheral A : RTS2 UART #2 Request to Send Signal
2 PA4 J10_2 J4_1
Peripheral B : MCDB2 Disabled.
Peripheral A : A24 External Address Bus
