14.1.1.6 CTS/RTS separate function (UART0)
This function separates CTS
from the P6
4
• 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 CTS
• UCON register's CLKMD1 bit = 0 (CLKS
Note that when using the CTS/RTS separate function, UART1 CTS/RTS separate function cannot be
used.
