(f) CTS/RTS separate function (UART0)
This function separates CTS0/RTS0, outputs RTS0 from the P60 pin, and accepts as input the CTS0
from the P64 pin. To use this function, set the register bits as shown below.
• U0C0 register's CRD bit = 0 (enables UART0 CTS/RTS)
• U0C0 register's CRS bit = 1 (outputs UART0 RTS)
• U1C0 register's CRD bit = 0 (enables UART1 CTS/RTS)
• U1C0 register's CRS bit = 0 (inputs UART1 CTS)
• UCON register's RCSP bit = 1 (inputs CTS0 from the P64 pin)
• UCON register's CLKMD1 bit = 0 (CLKS1 not used)
Note that when using the CTS/RTS separate function, UART1 CTS/RTS separate function cannot be
used.
