MPC5644A INTC_InstallINTCInterruptHandler

[wtlll]

When I want to initiate a new SCI.I found someone has the following codes：

void initESCI_B (void)
{
ESCI_B.CR2.R = 0x2000; /* Module is enabled (default setting ) */
ESCI_B.CR1.R = 0x01A1002C; /* 9600 baud, 8 bits, no parity, Tx & Rx enabled */
SIU.PCR[91].R = 0x400; /* Configure pad for primary func: TxDB */
SIU.PCR[92].R = 0x400; /* Configure pad for primary func: RxDB */
INTC_InstallINTCInterruptHandler(sci_Receive, 149, 1);
}

I want to know what's the meaning of the second variable 149.If I want to initiate a new SCI_B,which number should I choose for this variable.

INTC_InstallINTCInterruptHandler (name of the function, interrupt vector, priority).
