• Pins Used for Fujitsu Standard Serial On-board Programming
Pin
Function
Description
MD2,
MD1, MD0
Mode input pin
The device enters the serial program mode by setting MD2 = 1,
MD1 = 1 and MD0 = 0.
X0, X1 Oscillation pin
Because the internal CPU operation clock is set to be the 1 multiplication
PLL clock in the serial write mode, the internal operation clock frequency
is the same as the oscillation clock frequency.
P60, P61 Write program start pins Input a Low level to P60 and a High level to P61.
RST
Reset input pin
⎯
SIN0
SOT0
SCK0
Serial data input pin
Serial data output pin
Serial clock input pin
UART0 is used as CLK synchronous mode.
In write mode, the pins used for the UART0 CLK synchronous mode are
SIN0, SOT0, and SCK0.
When supplying the write voltage (MB90F337 : 3.3 V±0.3 V) from the
VCC
Power source input pin
user system, connection with the flash microcontroller programmer is
not necessary.
When connecting, do not short-circuit with the user power supply.
VSS
GND Pin
Share GND with the flash microcontroller programmer.
