16.6.1 RXD
16.6.2 TXD
16.7 Memory Map and Registers
NOTE:
RXD is the SCI receiver pin. RXD is available for general-purpose I/O
when it is not configured for receiver operation.
TXD is the SCI transmitter pin. TXD is available for general-purpose I/O
when it is not configured for transmitter operation.
Table 16-1 shows the SCI memory map.
Reading unimplemented addresses (0x00cc_000b through
0x00cc_000f) returns 0s. Writing to unimplemented addresses has no
effect. Accessing unimplemented addresses does not generate an error
response.
