Test mode input pin
This pin is used for testing this chip. For further details, refer to the S1C33 ASIC Design Guide.
DSIO I/O Pull-up Serial I/O pin for debugging
This pin is used to communicate with the debugging tool S5U1C33000H.
#X2SPD I – Clock doubling mode set-up pin1: CPU clock = bus clock × 1, 0: CPU clock = bus clock × 2
#NMI I Pull-up NMI request input pin
#RESET I Pull-up Initial reset input pin
Note: "#" in the pin names indicates that the signal is low active.
