MB91360G Series
105
(Continued)
*1 : The ICRs are located in the interrupt controller and set the interrupt level for each interrupt request. An ICR is
provided for each interrupt request.
*2 : The vector address for each EIT (exception, interrupt or trap) is calculated by adding the listed offset to the
table base register value (TBR) . The TBR specifies the top of the EIT vector table. The addresses listed in the
table are for the default TBR value (0x000FFC00H) . The TBR is initialized to this value by a reset.After execution
of the internal boot ROM TBR is set to 0x00FFC00H.
*3 : Used by REALOS
*4 : System reserved
*5 : Only available on MB91FV360GA
*6 : USART5/6 in MB91F364G, UART1/2 in all other devices.
*7 : DMA to/from the USARTs in MB91F364G is not implemented.
Remarks:
The 1-Kbyte area from the address specified in TBR is the EIT vector area.
Each vector consists of four bytes. The following formula shows the relationship between the vector number and
vector address.
vctadr = TBR + vctofs
= TBR + (3FCH - 4
× vct)
vctadr : Vector address, vctofs : Vector offset,
vct : Vector number
