(3) Internal Memory Interface Part
The internal memory interface part consists of the CPU register
and the memory channel controller.
qCPU register
The CPU register consists of the follows:
Memory channel operation mode register
Memory address counter
End address register
The CPU can set the beginning address into the memory address
counter when the memory channel operation enable bit
(MC_ENB) of EXB interrupt source enable register is “0”. When
this bit is “1”, the write operation from the CPU is invalid and each
access from the external bus causes count-up operation.
qMemory channel controller
The CPU register consists of the follows:
Main sequencer
Internal memory request signal generating circuit
External memory channel request signal generating circuit
Address end detection circuit
Terminal end input processing circuit
(4) Transmit/Receive Data Buffer Part
The transmit/receive data buffer part consists of the 8-bit transmit
buffer register (TXBUF) and the 8-bit receive buffer register
(RXBUF).
Both CPU channel and memory channel use the same transmit
buffer register/receive buffer register to transfer a data to an exter-
nal MCU bus.
(5) External Pin
The external bus interface has the following pins to connect with
an external MCU bus.
Chip select ........................... P34/ExCS
Address ................................ P37/ExA0
Data ...................................... P10/DQ0/AN0 to P17/DQ7/AN7
Read .................................... P36/ExRD
Write ..................................... P35/ExWR
Interrupt request .................. P33/ExINT
It also has the following pins to connect with an external DMAC.
Each pin can be programmed for an ordinary port function or a
DMA interface pin function.
DMA request ........................ P40/ExDREQ/RxD
DMA acknowledgment ......... P41/ExDACK/TxD
Terminal count ..................... P42/ExTC/SCLK
It also has the status read select pin (P43/ExA1/SRDY pin) to con-
firm a ready status of the data buffer from an external MCU bus
This pin functions as a port just after reset. The status read select
function can be set by a program.
Status read select ................ P43/ExA1/SRDY
qCPU channel: Communication with 38K0 group CPU
When a read/write operation is performed from an external MCU
bus in address signal ExA0 = “H”, the interrupt is generated and
the 38K0 group CPU can confirm its access. The 38K0 group CPU
judges the interrupt source and it starts a data transmission/recep-
tion with an external MCU bus.
qMemory channel: Communication with 38K0 group memory
multichannel RAM
When a read/write operation is performed from an external MCU
bus in address signal ExA0 = “L”, access to the multichannel RAM
is performed. Then an address of the multichannel RAM is made
by the external bus interface and it is increased at each access
completion. Consequently, FIFO access is performed.
Even if a read/write operation is performed in DACK = “L” instead
of ExCS = “L” and ExA0 = “L”, FIFO access to the multichannel
RAM is performed.
The beginning address and the end address must be set by the
CPU in advance.
