SPI/MICROWIRE-Compatible
UART in QSOP-16
POR
STATE
DESCRIPTION
0000
X
Pr
r
Receive-Parity Bit. This bit is the extra bit received if PE = 1. Therefore, PE = 1 results in 9-bit
transmissions (L = 0). If PE = 0, then Pr is set to 0. Pr is stored in the FIFO with the receive
data (see the
Nine-Bit Networks section).
0
IR
r
Reads the value of the IR bit.
L
READ/
WRITE
w
B0–B3
w
Baud-Rate Divisor Select Bits. Sets the baud clock’s value (Table 6).
B0–B3
r
Baud-Rate Divisor Select Bits. Reads the 4-bit baud clock value assigned to these registers.
BIT
NAME
Bit for setting the word length of the transmitted or received data. L = 0 results in 8-bit words
(9-bit words if PE = 1), see Figure 5. L = 1 results in 7-bit words (8-bit words if PE = 1).
0
X
L
r
Reads the value of the L bit.
Pt
w
Transmit-Parity Bit. This bit is treated as an extra bit that will be transmitted if PE = 1. To be
useful in 9-bit networks, the MAX3100 does not calculate parity. If PE = 0, then this bit (Pt) is
ignored in transmit mode (see the
Nine-Bit Networks section).
00000000
0
D0r–D7r
r
Eight data bits read from the receive FIFO or the receive register. These will be all 0s when
the receive FIFO or the receive registers are empty. When L = 1, D7r is always 0.
FEN
w
FIFO Enable. Enables the receive FIFO when FEN = 0. When FEN = 1, FIFO is disabled.
0
FEN
r
FIFO-Enable Readback. FEN’s state is read.
IR
w
Enables the IrDA timing mode when IR = 1.
No
change
X
CTS
r
Clear-to-Send-Input. Records the state of the CTS pin (CTS bit = 0 implies CTS pin = logic
high).
D0t–D7t
w
Transmit-Buffer Register. Eight data bits written into the transmit-buffer register. D7t is ignored
when L = 1.
Table 5. Bit Descriptions
0
PE
w
Parity-Enable Bit. Appends the Pt bit to the transmitted data when PE = 1, and sends the Pt
bit as written. No parity bit is transmitted when PE = 0. With PE = 1, an extra bit is expected to
be received. This data is put into the Pr register. Pr = 0 when PE = 0. The MAX3100 does not
calculate parity.
0
PE
r
Reads the value of the Parity-Enable bit.
0
PM
w
Mask for Pr bit. IRQ is asserted if PM = 1 and Pr = 1 (Table 6).
0
PM
r
Reads the value of the PM bit (Table 6).
0
R
r
Receive Bit or FIFO Not Empty Flag. R = 1 means new data is available to be read from the
receive register or FIFO.
0
RM
w
Mask for R bit. IRQ is asserted if RM = 1 and R = 1 (Table 6).
0
RM
r
Reads the value of the RM bit (Table 6).
0
RAM
w
Mask for RA/FE bit. IRQ is asserted if RAM = 1 and RA/FE = 1 (Table 6).
0
RAM
r
Reads the value of the RAM bit (Table 6).
0
RTS
w
Request-to-Send Bit. Controls the state of the RTS output. This bit is reset on power-up (RTS
bit = 0 sets the RTS pin = logic high).
