µPD17P709A
2. ONE-TIME PROM (PROGRAM MEMORY) WRITE, READ, AND VERIFY
The µPD17P709A includes a 16,384 × 16-bit one-time PROM program memory. In normal operation, this
PROM is accessed in 16-bit word units. During program memory write, read, and verify, the PROM is accessed
in 8-bit word units. The higher 8 bits of a 16-bit word are located at an even-numbered address, and the lower
8 bits are located at an odd-numbered address.
The pins used for the write, read, and verify operations of this one-time PROM are listed in Table 2-1.
Clock input from the CLK pin, instead of address input, is used for updating addresses.
