Function

Data bus I/O control 1 (SP = low)*1

Data bus I/O control 2 (SP = low)*1

DMA acknowledge (SP = low)*1

Write control signal (SP = low)*1

Read control signal (SP = low)*1

Address input 0 (SP = low) CCB CL input (SP = high)

1 (SP = low) CCB CE input (SP = high)

2 (SP = low) CCB DI input (SP = high)

3 (SP = low)*1

Chip select input (SP = L)*1

System reset input (negative logic)

Standby mode (positive logic)

I/O

Input

SP = low: parallel, SP = high: serial

BUSWD = low: 8 bits, BUSWD = high: 16 bits

The test pin must be connected to the digital system ground (VSS).

Must be connected to the digital system power supply (VDD) or ground

(VSS) in normal operation.

Input

Clock regeneration monitor

Demodulated data monitor

Frame start signal output

Block start signal output

Outputs a high level during frame synchronization

Outputs a high level during block synchronization

Level 4 CRC detection result output

External CPU interrupt request output

DMA request signal

Read ready signal

Output

Data bus

The bus width can be set to be either 8 bits or 16 bits by the BUSWD

pin (pin 48).

I/O

For data input, only the lower 8 bits (D0 to D7) are valid.

25 to 32

D8 to D15

Data bus (in 16-bit mode)

These pins are held in the output off state when BUSWD is low.

Output

64

XIN

Connections for the system clock crystal oscillator circuit.
