CC3135MOD
SWRS225B – FEBRUARY 2019 – REVISED MARCH 2020
Using 3-wire topology requires one of the following conditions to be met:
• Host always stays awake or active.
• Host goes to sleep, but the UART module has receiver start-edge detection for auto wake up and does
not lose data.
• Host can always receive any amount of data transmitted by the SimpleLink device because there is no
flow control in this direction.
Because there is no full flow control, the host cannot stop the SimpleLink device to send its data; thus, the
following parameters must be carefully considered:
• Maximum baud rate
• RX character interrupt latency and low-level driver jitter buffer
• Time consumed by the user's application
5.16.3 External Flash Interface
The CC3135MOD module includes the Macronix 32-Mbit Serial Flash. The Serial Flash can be
programmed directly via the external Flash interface (pins 13, 14, 15, and 17). Note that during normal
operation, the external Flash interface should remain unconnected.
