SMALLEST 2.25V TO 5.5V UART WITH 16-BYTE FIFO AND POWERSAVE
MSR[4]: CTS Input Status
CTS# pin may function as automatic hardware flow control signal input if it is enabled and selected by Auto
CTS (EFR bit-7). Auto CTS flow control allows starting and stopping of local data transmissions based on the
modem CTS# signal. A logic 1 on the CTS# pin will stop UART transmitter as soon as the current character
has finished transmission, and a logic 0 will resume data transmission. Normally MSR bit-4 bit is the
compliment of the CTS# input. However in the loopback mode, this bit is equivalent to the RTS# bit in the MCR
register. The CTS# input may be used as a general purpose input when the modem interface is not used.
MSR[5]: DSR Input Status
DSR# (active high, logical 1). Normally this bit is the compliment of the DSR# input. In the loopback mode, this
bit is equivalent to the DTR# bit in the MCR register. The DSR# input may be used as a general purpose input
when the modem interface is not used.
MSR[6]: RI Input Status
RI# (active high, logical 1). Normally this bit is the compliment of the RI# input. In the loopback mode this bit is
equivalent to bit-2 in the MCR register. The RI# input may be used as a general purpose input when the
modem interface is not used.
MSR[7]: CD Input Status
CD# (active high, logical 1). Normally this bit is the compliment of the CD# input. In the loopback mode this bit
is equivalent to bit-3 in the MCR register. The CD# input may be used as a general purpose input when the
modem interface is not used.
4.11
Scratchpad Register (SPR) - Read/Write
This is a 8-bit general purpose register for the user to store temporary data. The content of this register is
preserved during sleep mode but becomes 0xFF (default) after a reset or a power off-on cycle.
4.12
Baud Rate Generator Registers (DLL and DLM) - Read/Write
The concatenation of the contents of DLM and DLL gives the 16-bit divisor value which is used to calculate the
baud rate:
Baud Rate = (Clock Frequency / 16) / Divisor
See MCR bit-7 and the baud rate table also.
4.13
Device Identification Register (DVID) - Read Only
This register contains the device ID (0x01 for XR16L580). Prior to reading this register, DLL and DLM should
be set to 0x00.
4.14
Device Revision Register (DREV) - Read Only
This register contains the device revision information. For example, 0x01 means revision A. Prior to reading
this register, DLL and DLM should be set to 0x00.
4.15
Enhanced Feature Register (EFR)
Enhanced features are enabled or disabled using this register. Bit 0-3 provide single or dual consecutive
character software flow control selection (see
Table 10). When the Xon1 and Xon2 and Xoff1 and Xoff2 modes
are selected, the double 8-bit words are concatenated into two sequential characters. Caution: note that
whenever changing the TX or RX flow control bits, always reset all bits back to logic 0 (disable) before
programming a new setting.
EFR[3:0]: Software Flow Control Select
Single character and dual sequential characters software flow control is supported. Combinations of software
flow control can be selected by programming these bits.
