RxD
The UART baud rate clock is used by the IrDA endec to generate the demodulated signal
(RxD) that drives the UART. Each UART bit period is sixteen baud-clocks wide. Each
IR_RXD bit is encoded during a bit period such that a 0 is represented by a pulse and a 1
is represented by no pulse. The IrDA Physical Layer Specification describes a nominal
pulse as being
(Low), a 3-clock-wide Low (0) pulse is received following a 7-clock High (1) period. Fol-
lowing the 3-clock Low pulse is a 6-clock High pulse to complete the full 16-clock data
period. If the data to be received is a logical 1 (High), the IR_RxD signal is held High (1)
for the full 16-clock period. Data reception is illustrated in Figure 27.
The IrDA Physical Layer Specification allows for a minimum signal width as well as the
nominal signal width described above. By definition, the received pulse duration can be as
small as 1.41 seconds for all baud rates up to 115.2 KBPS. IrDA Physical Layer 1.4 Pulse
Durations Specifications outlines the minimum and maximum pulse durations for all baud
rates supported by the eZ80
clock frequency measures this time limit and allows legal signals to pass to UART0.
