I/O
Serial data pin. Output port when reading and input
port when writing. Can be assigned as a Input/push-
pull output port.
P0.6
SCLK
14
I/O
Serial clock pin. Input only pin.
TEST
V
PP (TEST)
19
I
Power supply pin for FLASH ROM cell writing
(indicates that FLASH enters into the writing mode).
When 12.5 V is applied, FLASH is in writing mode
and when 5 V is applied, FLASH is in reading
mode. When FLASH is operating, hold GND.
