Description
Power supply input
VCC
VSS
Apply 1.8 V to 5.5 V to the VCC pin.
Apply 0 V to the VSS pin.
CNVSS
This pin controls the operating mode of the chip.
Connect to the VSS pin.
Reset input
RESET
I
Driving this pin low resets the MCU.
XIN clock input
XIN

I/O ports
R38F3 Group
P00 to P07,
P10 to P17
I/O
I/O ports. Each port can be individually programmed as either input or
output in bit units. The output format is CMOS 3-state. A pull-up
resistor is enabled or disabled in bit units. P00 to P07 can be used to
output the large current for LED drive.
P21,
P30, P31
I/O ports. Each port can be individually programmed as either input or
output in bit units. The output format is CMOS 3-state.
R38F2 Group
P00 to P07,
P10 to P15
I/O ports. Each port can be individually programmed as either input or
output in bit units. The output format is CMOS 3-state. A pull-up
resistor is enabled or disabled in bit units. P00 to P07 can be used to
output the large current for LED drive.
P21
I/O port. Each port can be individually programmed as either input or
output in bit units. The output format is CMOS 3-state.
R38F1 Group
P00,
P03 to P07,
P10 to P13
I/O ports. Each port can be individually programmed as either input or
output in bit units. The output format is CMOS 3-state. Any input port
can be set to use/not use a pull-up resistor in bit units. P00, P03 to
P07 can be used to output the large current for LED drive.
P21
I/O port. Each port can be individually programmed as either input or
output in bit units. The output format is CMOS 3-state.
Output ports
P20
O
Output-only port. The output format is CMOS 3-state.
P22
Output-only port. The output format is N-channel open drain.
