10.1 SIO registers

Each SIO port has the following set of registers.

STB0-3: SIO transmit buffers

STB0-3 buffers contain the data to be transferred to the SIO transmit shift register.

SIO0 registers

• (STB0: Address = 0068h, reset value = 0000 h, write only)

• (STB1: Address = 0069h, reset value = 0000 h, write only)

• (STB2: Address = 006Ah, reset value = 0000 h, write only)

• (STB3: Address = 006Bh, reset value = 0000 h, write only)

SIO1 registers

• (STB0: Address = 00E8 h, reset value = 0000 h, write only)

• (STB1: Address = 00E9 h, reset value = 0000 h, write only)

• (STB2: Address = 00EA h, reset value = 0000 h, write only)

• (STB3: Address = 00EB h, reset value = 0000 h, write only)

SRB0-3: SIO receive buffers

SRB0-3 buffers contain the data transferred from the SIO receive shift register.

SIO0 registers

• (SRB0: Address = 006Ch, reset value = xxxx h, read only)

• (SRB1: Address = 006Dh, reset value = xxxx h, read only)

• (SRB2: Address = 006Eh, reset value = xxxx h, read only)

• (SRB3: Address = 006Fh, reset value = xxxx h, read only)

SIO1 registers

• (SRB0: Address = 00EC h, reset value = xxxx h, read only)

• (SRB1: Address = 00ED h, reset value = xxxx h, read only)

• (SRB2: Address = 00EE h, reset value = xxxx h, read only)

• (SRB3: Address = 00EF h, reset value = xxxx h, read only)
