Loopback Testing
If this equation results in a value less than one, MIN_PULSE must be set to 0x0h which
enables edge detection and ensures that valid pulses wider than W
field's maximum setting of 0xFh supports a W
Due to the inherent sampling of the received IR_RxD signal by the Bit Rate Clock, some
jitter is expected on the first bit in any sequence of data. However, all subsequent bits in
the received data stream are a fixed 16 clock periods wide.
The endec signal pins, IR_TxD and IR_RxD, are multiplexed with General-Purpose
Input/Output (GPIO) pins. These GPIO pins must be configured for alternate function
operation for the endec to operate.
The remaining six UART0 pins, CTS0, DCD0, DSR0, DTR0, RTS, and RI0, are not
required for use with the endec. The UART0 modem status interrupt must be disabled to
prevent unwanted interrupts from these pins. The GPIO pins corresponding to these six
unused UART0 pins are used for inputs, outputs, or interrupt sources. Recommended
GPIO Port D control register settings are listed in
Output
Both internal and external loopback testing is accomplished with the endec on the eZ80F91
device. Internal loopback testing is enabled by setting the LOOP_BACK bit to 1. During
internal loopback, the IR_TxD output signal is inverted and connected on-chip to the
IR_RxD input. External loopback testing of the off-chip IrDA transceiver is accomplished
by transmitting data from the UART while the receiver is enabled (IR_RxEN set to 1).
