4.11 MTU2 Interface

The SH7264 includes a Multi Function Timer Pulse Unit 2 (MTU2) consists of five channels of 16-bit timer counter. LEDs are
connected to MTU2 pins to control LED brightness on the M3A-HS64G02. MTU2 pins are also used as SDRAM control pins
and RSPI (Renesas Peripheral Interface) channel 0 pin. The figure below shows the MTU2 interface block diagram. The table
below lists the DIP switches setting (SW5 on the M3A-HS64).
