SBI0CR2
(0xFFFF_F243) Read/Write
Note 1: When read, this register functions as the SBI0SR register.
Note 2: Check to see that the bus is free before switching the device to port mode. Also, check that input
signals on the ports are High before switching from port mode to I
clock-synchronous 8-bit SIO mode.
Note: The – character means “Don’t use”.
