• Manufacturer Part Number: UPD64084
• Description: THREE-DIMENSIONAL Y/C SEPARATION LSI WITH ON-CHIP MEMORY
• Manufacturer: NEC

subaddress is specified in this mode. Transmission begins always at address 0. Before establishing a stop condition,
the master IC must send no-acknowledgment and release the SDA line.

(2) Read mode format (transmission mode for slaves)
If a slave IC receives its read-mode slave address in byte 1, it sends data in byte 2 and the subsequent bytes. No
Remark
The serial bus registers are initialized when the PD64084 is reset (RSTB). The I
