NMR[0]: 9-bit mode enable
logic 0
9-bit mode is disabled.
logic 1
9-bit mode is enabled.
NMR[1]: Enable interrupt when 9
th
bit is set
logic 0
Receiver interrupt for detection of an ‘a(chǎn)ddress’
character (i.e. 9
th
bit set) is disabled.
logic 1
Receiver interrupt for detection of an ‘a(chǎn)ddress’
character (i.e. 9
th
bit set) is enabled and a level
1 interrupt is asserted.
Special Character Detection
While the UART is in both 9-bit mode and Enhanced mode,
setting IER[5] will enable detection of up to four ‘a(chǎn)ddress’
characters. The least significant eight bits of these four
programmable characters are stored in special characters
1 to 4 (XON1, XON2, XOFF1 and XOFF2 in 650 mode)
registers and the 9
th
bit of these characters are
programmed in NMR[5] to NMR[2] respectively.
NMR[2]: Bit 9 of Special Character 1
NMR[3]: Bit 9 of Special Character 2
NMR[4]: Bit 9 of Special Character 3
NMR[5]: Bit 9 of Special Character 4
NMR[7:6]: Reserved
Bits 6 and 7 of NMR are always cleared and reserved for
future use.
7.11.10 Modem Disable Mask ‘MDM
The MDMregister is located at offset 0x0E of the ICR
This register is cleared after a hardware reset to maintain
compatibility with 16C550. It allows the user to mask
interrupts, sleep operation and power management events
due to individual modemlines or the serial input line.
MDM[0]: Disable delta CTS
logic 0
Delta CTS is enabled. It can generate a level 4
interrupt when enabled by IER[3]. In power-
state D2, delta CTS can assert the PME#line.
Delta CTS can wake up the UART when it is
asleep under auto-sleep operation.
logic 1
Delta CTS is disabled. In can not generate an
interrupt, assert a PME#or wake up the UART.
MDM[1]: Disable delta DSR
logic 0
Delta DSR is enabled. It can generate a level 4
interrupt when enabled by IER[3]. In power-
state D2, delta DSR can assert the PME#line.
Delta DSR can wake up the UART when it is
asleep under auto-sleep operation.
logic 1
Delta DSR is disabled. In can not generate an
interrupt, assert a PME#or wake up the UART.
MDM[2]: Disable Trailing edge RI
Data Sheet Revision 1.1
Page 49
OXCB950
OXFORD SEMICONDUCTOR LTD.
logic 0
Trailing edge RI is enabled. It can generate a
level 4 interrupt when enabled by IER[3]. In
power-state D2, trailing edge RI can assert the
PME#line. Trailing edge RI can wake up the
UART when it is asleep under auto-sleep
operation.
logic 1
Trailing edge RI is disabled. In can not
generate an interrupt, assert a PME#or wake
up the UART.
MDM[3]: Disable delta DCD
logic 0
Delta DCD is enabled. It can generate a level 4
interrupt when enabled by IER[3]. In power-
state D2, delta DCD can assert the PME#line.
Delta DCD can wake up the UART when it is
asleep under auto-sleep operation.
logic 1
Delta DCD is disabled. In can not generate an
interrupt, assert a PME#or wake up the UART.
MDM[4]: Reserved
This bit must be set to ‘0’
MDM[5]: Disable SIN wake up
logic 0
When the device is in power-down state D2, a
change in the state of the serial input line (i.e.
start bit) can assert the PME#line
logic 1
When the device is in power-down state D2, a
change in the state of the serial input line
cannot assert the PME#line.
MDM[7:6]: Reserved
7.11.11 Readable FCR ‘RFC’
The RFC register is located at offset 0x0F of the ICR
This read-only register returns the current state of the FCR
register (Note that FCR is write-only). This register is
included for diagnostic purposes.
7.11.12 Good-data status register ‘GDS’
The GDS register is located at offset 0x10 of the ICR
For the definition of Good-data status refer to section
Error! Reference source not found.
