Tx Polarity

Typically part of a 16C550A Serial Port Option

Register. The value also appears in CIrCC

Register Block One, Address Zero.

Rx Polarity

Typically part of a 16C550A Serial Port Option

Register. The value also appears in CIrCC

Register Block One, Address Zero.

Half Duplex

Typically part of a 16C550A Serial Port Option

Register. The value also appears in CIrCC

Register Block One, Address Zero.

IR Half Duplex Timeout

Typically part of a 16C550A Serial Port 2

Configuration Register. The value also appears

in CIrCC Register Block One, Address Zero.

IR Mode

Typically part of a 16C550A Serial Port Option

Register. These values are also part of the

CIrCC Block Control bits 3-5, Register Block

One, Address Zero.

IR Location

Typically part of a 16C550A Serial Port IR Option

Register. These values are the CIrCC Output

Mux bits, Register Block One, Address One.

Note: These legacy controls are uniformly

updated in the CIrCC and the Top-Level Device

Configuration Registers only when either set of

registers is explicitly written using IOW or

following a device-level POR. CIrCC software

resets will not affect the legacy bits.
