The PD78P058F has an on-chip 60-Kbyte PROM as a program memory. For programming, set the PROM
When +5 V or +12.5 V is applied to the V
Further, when the read mode is set, it is possible to read the contents of the PROM.
Operating Modes
Program writing should be performed in the address range 0000H to EFFFH (the last address,
EFFFH, should be specified). Writing cannot be performed with a PROM programmer that cannot
specify the write addresses.
