circuit, and a transmit buffer and its accompanying control circuit. All channels operate independently of each
other. Because all channels operate in the same way, this section consists only of an explanation for SIO0.
The TMP1942 contains five serial input/output channels: SIO0, SIO1, SIO3, SIO4 and SIO5. Each channel
In modes 1 and 2 a parity bit can be added. Mode 3 supports a wake-up function which is used by the master
Each channel consists of a prescaler, a serial clock generator, a receive buffer and its accompanying control
• Mode 0 (I/O interface mode): LSB first
• Mode 0 (I/O interface mode): MSB first
• Mode 1 (7-bit UART mode)
• Mode 2 (8-bit UART mode)
• Mode 3 (9-bit UART mode)
