LC895196

MCK2 (output)

This outputs the XTALCK0, XTALCK0/2, XTALCK0/5 and XTALCK0/512 frequencies. The output can also be

turned off.

MCK3 (output)

This outputs the XTALCK0, XTALCK0*2/5, XTALCK0/5 and XTALCK0/512 frequencies. The output can also be

turned off.

ZRSTIC (output)

The ZRSTIC output goes low when the microcontroller register R46-bit7 (ZSYSRES) or the ZHRST pin is put low.

When both the ZSYSRES and ZHRST pins are high, ZRSTIC enters a high impedance state. Attach and external

pull-up resistor.

ZRSTCPU (output)

When an ATAPI soft reset command (08h) is received, a low pulse is generated for approximately 1 ms (when

XTALCK1 = 34 MHz). When this happens, an interrupt is sent to the microcontroller. When the ZRESET pin has

become active, the ZRESET signal is output directly at the ZRSTCPU. Attach an external pull-up resistor.

ATPINSEL (input)

By changing the input to this pin, the ATAPI-side pin layout can be reversed.
