and automotive applications, such as electric metering, home appliances, HVAC systems, and entry level
instrument cluster. The MC9S08LG32 has 32 KB of on-chip programmable flash memory and 2 KB of
RAM available.
The MC9S08LG32 provides an LCD driver module, configurable up to 8 × 37 or 4 × 41. The LCD driver
module remains active even in low-power modes. It also includes an internal regulated charge pump for
contrast control. All LCD pins are multiplexed with GPIOs.
TSSEVB uses the MC9S08LG32 Inter-Integrated Circuit (IIC) module to establish communication with
the MC9S08JM60 Comm MCU when the TSSEVB is used along with EGT. To use the IIC module with
the EGT, jumpers on headers J10 and J11 respectively must be properly configured. For more information
on jumper configurations, refer to
The EVB includes two MC9S08JM60 MCUs, one is open source BDM that is used to program and debug,
while the other is used to communicate with the EGT GUI on a PC.
The MC9S08LG32 includes a Serial Communication Interface (SCI) module. The SCI module can be
connected to both MC9S08JM60 MCUs included in the TSSEVB and you can select either by changing
the position on J1 and J2 jumpers. The SCI module is included in the TSSEVB for future demo
applications.
MC9S08LG32 is packaged in an 80-pin quad flat non-lead package (QFN).
2.1.3
MC9S08LG32 has nine I/O ports that include a total of up to 69 GPIO pins. Most of these pins are shared
with the on-chip peripherals such as timer systems, external interrupts, or keyboard interrupts. When these
modules are not controlling the port pins, they revert to GPIO control. Immediately after reset, all 69 GPIO
pins are configured as high-impedance general-purpose inputs with internal pull-up devices disabled. The
port allocation of the general-purpose I/O and on-chip peripheral functions on the EVB are listed in
