Operation

This section describes the functions and basic operational blocks of the TMP93PW32.

The TMP93PW32 has PROM in place of the mask ROM which is included in the TMP93CS32.

The other configuration and functions are the same as the TMP93CS32. Regarding the functions of

the TMP93PW32 (Not described), see the part of TMP93CS32.

The TMP93PW32 has two operational modes: MCU mode and PROM mode.

3.1

MCU Mode

(1) Mode-setting and function

The MCU mode is set by opening the CLK pin (Pin open). In the MCU mode, the

operation is same as TMP93CS32 except the followings.

(2) Memory map

The memory map of TMP93PW32 is not same as that of TMP93CS32.

Figure 3.1.1 shows the memory map in MCU mode. Figure 3.1.2 show that in PROM

mode.
