24 / 60 page ![]() EM62100 65 COM/132 SEG STN LCD Driver 18 • ••• Product Specification (V1.1) 09.13.2005 (This specification is subject to change without further notice) When several EM62100 chips are used, the slave chips must supply the display timing signals (M, CK, DOFB) from the master chip. Explanation is shown in Table 6. Table 6 Operating Mode M CK DOFB Master (M/S= “H”) The internal oscillator circuit is enabled (CKS=”H”) The internal oscillator circuit is disabled (CKS=”L”) O O O I O O Slave (M/S = “L”) The internal oscillator circuit is enabled (CKS=”H”) The internal oscillator circuit is disabled (CKS=”L”) I I I I I I O: Output, I: Input NOTE When the EM62100 is used in the master/slave configuration, each of the CKS pins are set to the same level together. Table 7 shows the relationship between the oscillation frequency and frame frequency. fOSC which can be selected as 31.4 or 26.3kHz by using Oscillation Frequency Select command. Table 7 Duty Item fCK fM On-chip oscillator is used fOSC/6 fCK / (2 x 65) 1/65 On-chip oscillator is not used External input fCL fCK / (2 x 65) On-chip oscillator is used fOSC/7 fCK / (2 x 55) 1/55 On-chip oscillator is not used External input fCL fCK / (2 x 55) On-chip oscillator is used fOSC/8 fCK / (2 x 49) 1/49 On-chip oscillator is not used External input fCL fCK / (2 x 49) On-chip oscillator is used fOSC/12 fCK / (2 x 33) 1/33 On-chip oscillator is not used External input fCL fCK / (2 x 33) On-chip oscillator is used fOSC/22 fCK / (2 x 17) 1/17 On-chip oscillator is not used External input fCL fCK / (2 x 17) On-chip oscillator is used fOSC/44 fCK / (2 x 9) 1/9 On-chip oscillator is not used External input fCL fCK / (2 x 9) |
