7.1.4 Logical Device 3 (UART B)
CR30 (Default 0x01 if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 1 : Reserved.
Bit 0 = 1 Activates the logical device.
= 0 Logical device is inactive.
CR60, CR 61 (Default 0x02, 0xF8 if PNPCSV = 0 during POR, default 0x00, 0x00 otherwise)
These two registers select Serial Port 2 I/O base address [0x100:0xFF8] on 8 byte boundary.
CR70 (Default 0x03 if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 4 : Reserved.
Bit [3:0] : These bits select IRQ resource for Serial Port 2.
CRF0 (Default 0x00)
Bit 7 - 4 : Reserved.
Bit 3 : RXW4C
= 0 No reception delay when SIR is changed from TX mode to RX mode.
= 1 Reception delays 4 characters - time (40 bit-time) when SIR is changed from TX
mode to RX mode.
Bit 2 : TXW4C
= 0 No transmission delay when SIR is changed from RX mode to TX mode.
= 1Transmission delays 4 characters-time (40 bit-time) when SIR is changed from RX
mode to TX mode.
Bit 1 - 0 : SUBCLKB1, SUBCLKB0
= 00 UART B clock source is 1.8462 Mhz (24MHz/13)
= 01 UART B clock source is 2 Mhz (24MHz/12)
= 10 UART B clock source is 24 Mhz (24MHz/1)
= 11 UART B clock source is 14.769 Mhz (24mhz/1.625)
CRF1 (Default 0x00)
Bit 7 : Reserved.
Bit 6 : IRLOCSEL. IR I/O pins' location select.
= 0 Through SINB/SOUTB.
= 1 Through IRRX/IRTX.
Bit 5 : IRMODE2. IR function mode selection bit 2.
Bit 4 : IRMODE1. IR function mode selection bit 1.
Bit 3 : IRMODE0. IR function mode selection bit 0.
