Universal Serial Bus Series Microcontroller
5 Pin Description
Symbol
I/O
Function
P50 ~ P57
I/O General 8-bit bidirectional input/output port. All pins on this port can
be internally pulled-high by software control.
P60 ~ P67
P70 ~ P72
P76 ~ P77
P80 ~ P87
P90 ~ P93
P95 ~ P96
I/O General 8-bit bidirectional input/output port. All pins on this port can
be internally pulled-high by software control.
LED sink pins
I/O P76 ~ P77 will have an internally pulled-high resistor when the
EM78M611E is running in PS/2 mode.
I/O General 8-bit bidirectional input/output port. All pins on this port can
be internally pulled-high by software control.
I/O General 6-bit bidirectional input/output port. All pins on this port can
be internally pulled-high by software control or LED sink pins.
P94 / Vpp
I Input only. MTP program pin.
PWM1
PWM2
O PWM output pins.
USB plus data line interface or CLK for PS/2 keyboard.
D+/CLK/P74 I/O When the EM78M611E is running in PS/2 mode, this pin will have an
internal pulled-high resistor (2.2KΩ), with VDD=5.0V.
USB minus data line interface or DATA for PS/2 keyboard.
When the EM78M611E is running in PS/2 mode, this pin will have an
D-/DATA/P75 I/O internal pulled-high resistor (2.2KΩ), with V3.3=3.3V.
When the EM78M611E is running in USB mode, this pin will have an
internal pulled-high resistor (1.5KΩ), with VDD=3.3V.
OSCI
I 6MHz / 12MHz ceramic resonator input.
OSCO
O Return path for 6MHz / 12MHz ceramic resonator.
VNN
MTP program pin. Used in programming the on-chip ROM. During
normal operation, this pin is connected to Ground.
V3.3
PWR 3.3V regulator output
VDD
GND
PWR Power supply pin
PWR Ground pin
