13.4 Logical Device 2 (UART A)
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 0x03, 0xF8 if PNPCSV = 0 during POR, default 0x00, 0x00 otherwise)
These two registers select Serial Port 1 I/O base address [0x100:0xFF8] on 8 byte boundary.
CR70 (Default 0x04 if PNPCSV = 0 during POR, default 0x00 otherwise)
Bit 7 - 4
: Reserved.
Bit 3 - 0
: These bits select IRQ resource for Serial Port 1.
CRF0 (Default 0x00)
Bit 7 - 2
: Reserved.
Bit 1 - 0
: SUACLKB1, SUACLKB0
= 00 UART A clock source is 1.8462 MHz (24MHz/13)
= 01 UART A clock source is 2 MHz (24MHz/12)
