Data Bus
This is a data bus to access the register from the system bus.
Data Bus / Port Signal
P6 to P0 are used as port signals when selected to 8-bit bus interface.
D14 to D8 are used as data signals when selected to 16-bit bus interface.
D15 Signal / A0 Signal
A0 (LSB) is used as an address signal when selected to 8-bit bus interface.
D15 (MSB) is used as an data signal when selected to 16-bit bus interface.
Address Bus
This is an address bus to access the register from the system bus.
Chip Select
"L" level enables communication with the M66291.
Low-write Strobe
The lower data (D7 to D0) is written to the register at “L” level.
High-write Strobe / Bus Width Select
With the reset signal set to “H” level, the 8-bit bus interface is selected if this
pin is at “L” level. Further, if this pin is at “H” level, the 16-bit bus interface is
selected. When the 16-bit bus interface is selected, the upper data (D15 to
D8) is written to the register at “L” level.
Fix to “L” level when set to 8-bit bus interface.
Read Strobe
Data are read from registers at "L" level
Interrupt 0
Interrupts are requested to the system at "L" level.
Interrupt 1 / SOF Output
This pin is used as an interrupt 1 or as a SOF output pin to transmit USB SOF
signal according to register setting.
DMA Request 0
This pin is used to request DMA transfer to endpoint FIFO for DMA channel 0.
DMA Acknowledge 0
This pin enables access of FIFO by DMA transfer for DMA channel 0.
DMA Request 1
This pin is used to request DMA transfer to endpoint FIFO for DMA channel 1.
