UBCR
UBCR is a 3 bits register which is used to select clock source to
generate suitable baud rate:
000: 15Mhz from external crystal
100: 30Mhz divided from PLL 480Mhz
101: 43.6Mhz divided from PLL 480Mhz
110: 48Mhz divided from PLL 480Mhz
111: 60Mhz divided from PLL 480Mhz
6.12.3 UART2
UART2 contains 2 features: general UART and IrDA SIR decoder/encoder. UART has not modem
function. Please read the spec of section 7.12.5 General UART controller function description. The
IrDA SIR is described as follow:
