DESCRIPTION
Received parity bit = 1
Transition on RX when
in shutdown; framing
error when not in
shutdown
RA/FE
RAM
This is the RA (RX-transition) bit in shutdown, and the FE (framing-error) bit in
operating mode. RA is set if there has been a transition on RX since entering
shutdown. RA is cleared when the MAX3100 exits shutdown. IRQ is asserted
when RA is set and RAM = 1.
FE is determined solely by the currently received data, and is not stored in FIFO.
The FE bit is set if a zero is received when the first stop bit is expected. FE is
cleared upon receipt of the next properly framed character. IRQ is asserted
when FE is set and RAM = 1.
MASK
BIT
Pr
PM
The Pr bit reflects the value in the word currently in the receive-buffer register
(oldest data available). The Pr bit is set when parity is enabled (PE = 1) and the
received parity bit is 1. The Pr bit is cleared either when parity is not enabled (PE
= 0), or when parity is enabled and the received bit is 0. An interrupt is issued
based on the oldest Pr value in the receiver FIFO. The oldest Pr value is the next
value that will be read by a Read Data operation.
BIT
NAME
Data available
R
RM
The R bit is set when new data is available to be read from the receive register/
FIFO. FIFO is cleared when all data has been read. An interrupt is asserted as long
as R = 1 and RM = 1.
Transmit buffer is
empty
T
TM
The T bit is set when the transmit buffer is ready to accept data. IRQ is asserted
low if TM = 1 and the transmit buffer becomes empty. This source is cleared on
CS’s rising edge during a Read Data operation. Although the interrupt is cleared,
T may be polled to determine transmit-buffer status.
Interrupt Sources and Masks
A Read Data operation clears the interrupt IRQ. Table
6 gives the details for each interrupt source. Figure 6
shows the functional diagram for the interrupt sources
and mask blocks.
