Programmer Mode
In programmer mode, a PROM programmer can be used to perform programming/erasing via a
socket adapter, just as a discrete flash memory. Use a PROM programmer that supports the MCU
device type with the on-chip Renesas Technology (former Hitachi Ltd.) 64-Kbyte flash memory
(F-ZTAT64V3). A 10-MHz input clock is required. For the conditions for transition to
programmer mode, see table 6.7.
6.10.1
Socket Adapter
The socket adapter converts the pin allocation of the HD64F38024, HD64F38024R, and
HD64F38124 to that of the discrete flash memory HN28F101. The address of the on-chip flash
memory is H'0000 to H'7FFF. Figure 6.12(1) shows a socket-adapter-pin correspondence diagram
of the HD64F38024 and HD64F38024R. Figure 6.12(2) shows a socket-adapter-pin
correspondence diagram of the HD64F38124.
6.10.2
Programmer Mode Commands
The following commands are supported in programmer mode.
• Memory Read Mode
• Auto-Program Mode
• Auto-Erase Mode
• Status Read Mode
Status polling is used for auto-programming, auto-erasing, and status read modes. In status read
mode, detailed internal information is output after the execution of auto-programming or auto-
erasing. Table 6.13 shows the sequence of each command. In auto-programming mode, 129 cycles
are required since 128 bytes are written at the same time. In memory read mode, the number of
cycles depends on the number of address write cycles (n).
