14.1.2.6 CTS/RTS Separate Function (UART0)
This function separates CTS
from the P6
• The CRD bit in the U0C0 register is set to "0" (enables UART0 CTS/RTS)
• The CRS bit in the U0C0 register is set to "1" (outputs UART0 RTS)
• The CRD bit in the U1C0 register is set to "0" (enables UART1 CTS/RTS)
• The CRS bit in the U1C0 register is set to "0" (inputs UART1 CTS)
• The RCSP bit in the UCON register is set to "1" (inputs CTS
• The CLKMD1 bit in the UCON register is set to "0" (CLKS
Note that when using the CTS/RTS separate function, UART1 CTS/RTS separate function cannot be
used.

NOTES:
1. This applies to the case where the U1MAP bit in the PACR register is set to "0" (P6
