In shared memory write operations, the actual write to memory is executed after HMEMWR is inactive. In case reset or entering Idle mode occurs before the memory write cycle is completed it may be that the data will not be written to memory. 3. n is the number of clock cycles, as programmed in the IDB field. See PS/2 Control Register in Section 12.5.3 on page 95. 4. n is the number of clock cycles, as programmed in the IDB field. See PS/2 Control Register in Section 12.5.3 on page 95. 5. Refer to Table 7-1 on page 76 for the definition of tCLKINTnom. 6. Depends on the signal capacitance and the pull-up value. 7.
