MAX 3100 Operations
Write Operations
Table 1 shows write-configuration data. A 16-bit
SPI/Microwire write configuration clears the receive
FIFO and the R, T, RA/FE, D0r–D7r, D0t–D7t, Pr, and Pt
registers.
RTS
and
CTS
remain unchanged. The new
configuration is valid on
CS
’s rising edge if the transmit
buffer is empty (T = 1) and transmission is over. If the
latest transmission has not been completed, the regis-
ters are updated when the transmission is over (T = 0).
The write-configuration bits (
FEN
, SHDNi, IR, ST, PE, L,
B3–B0) take effect after the current transmission is
over. The mask bits (
TM
,
RM
,
PM
,
RAM
) take effect
immediately after the 16th clock’s rising edge at SCLK.
Read Operations
Table 2 shows read-configuration data. This register
reads back the last configuration written to the
MAX3100. The device enters test mode if bit 0 = 1. In
this mode, if
CS
= 0, the
RTS
pin acts as the 16x clock
generator’s output. This may be useful for direct baud-
rate generation (in this mode, TX and RX are in digital
loopback).
Normally, the write-data register loads the TX-buffer
register. To change the
RTS
pin’s state without writing
data, set the
TE
bit. Setting the
TE
bit high inhibits the
write command (Table 3).
Reading data clears the R bit and interrupt
IRQ
(Table 4).
Register Func tions
Table 5 shows read/write operation and power-on reset
state (POR), and describes each bit used in program-
ming the MAX3100. Figure 5 shows parity and word-
length control.
