95 / 358 page  FUNCTIONAL DESCRIPTION Rev.2.00 Oct 15, 2006 page 76 of 130 38K2 Group REJ09B0338-0200 HARDWARE EXB Register List The EXB register list is shown below. Fig. 107 EXB related registers (1) •EXB interrupt source enable register This register enables/disables access from an external bus and an internal interrupt. •EXB interrupt source register This register indicates the state of CPU channel’s transmit/receive buffer register and the memory channel. The same value can be read out from the external MCU bus by using the buffer status read select signal (A1 pin = “H”). •EXB index register/Register windows 1, 2 The accessible register is switched by treating addresses 003416 and 003516 as a register window depending on the value of EXB index register at address 003316. •External I/O configuration register This register selects the function of each pin. •Transmit/Receive buffer register This register consists of the receive buffer register (RXBUF) and the transmit buffer register (TXBUF) •Memory channel operation mode register This register sets the operation mode of the memory channel. •Memory address counter This is a counter to set the beginning address which FIFO ac- cesses. This register is increased by access from the external MCU bus. •End address register This register is to set the end address which FIFO accesses.
