PROM Mode Pin Functions
V_PP: Applies the programming voltage (12.5 V ± 0.3 V) to the built-in PROM.
CE: Inputs a control signal to enable PROM programming and verification.
OE : Inputs a data output control signal for verification.
A₀–A₁₄: Act as address input pins of the built-in PROM.
O₀–O₇: Act as data bus input pins of the built-in PROM. Each of O₀–O₄ has two pins; before using these
pins, connect each pair together.
M₀ , M₁, RESET, TEST: Used to set PROM mode. The MCU is set to the PROM mode by pulling M₀,
M₁, and TEST low, and RESET high.
Other Pins (FP-100B/FP-100A): Connect pins 1/3 (AV_CC), 8/10 (OSC₁), 16/18 (D₂), 17/19 (D₃), 53/55
(R6₃/SEG16), and 97/99 (V_CC) to V_CC, and pins 6/8 (AV_SS) and 11/13 (X1) to GND. Leave other pins
open.
