UART Modules
15.2.3
The Request-To-Send (RTS) pins DDATA3/RTS0/GPIO4 and DDATA1/RTS1/SDATA2_BS2/GPIO2 are
multiplexed. When programmed for RTS, this active-low output signal can be programmed to be
automatically negated and asserted by either the receiver or transmitter. When connected to the
clear-to-send (CTS) input of a transmitter, this signal controls serial data flow.
UART2 has no RTS signal capability.
15.2.4
The multiplexed signals DDATA2/CTS0/GPIO3 and DDATA0/CTS1/SDATA0_SDIO1/GPIO1 can be
programmed as general purpose inputs or Clear-To-Send inputs. When programmed as (CTS), this
active-low input is the clear-to-send input and can generate an interrupt on change-of-state.
UART2 has no CTS signal capability.
