Description
48-Pin 32-Pin
VDD

Digital Voltage Supply.
GND

9
Ground. (
Note: Pins 5,6, and 8 on the 48-pin package are not
connected (NC), but it is recommended that they be connected to
ground.)
MONEN
12
D In
Monitor Enable (on 48 pin package ONLY). Enables reset volt-
age monitor function when pulled high (logic “1”).
TCK

D In
JTAG Test Clock with internal pull-up.
TMS
26
18
D In
JTAG Test-Mode Select with internal pull-up.
TDI
28
20
D In
JTAG Test Data Input with internal pull-up. TDI is latched on a
rising edge of TCK.
TDO
27
19
D Out JTAG Test Data Output. Data is shifted out on TDO on the falling
edge of TCK. TDO output is a tri-state driver.
XTAL1
9
6
A In
Crystal Input. This pin is the return for the internal oscillator cir-
cuit for a crystal or ceramic resonator. For a precision internal
clock, connect a crystal or ceramic resonator from XTAL1 to
XTAL2. If overdriven by an external CMOS clock, this becomes
the system clock.
XTAL2
10
7
A Out
Crystal Output. This pin is the excitation driver for a crystal or
ceramic resonator.
RST
14
10
D I/O
Chip Reset. Open-drain output of internal Voltage Supply moni-
tor. Is driven low when VDD is < 2.7V and MONEN=1, or when a
‘1’is written to PORSF. An external source can force a system
reset by driving this pin low.
VREF
7
5
A I/O
Voltage Reference. When configured as an input, this pin is the
voltage reference for the ADC. Otherwise, VDD will be the refer-
ence. NOTE: this pin is Not Connected (NC) on ‘F230/1/6.
