Pull-up resistor input, pull-down resistor input, or high-impedance input is selectable for each bit. Applied to the ML63189B only. 4-bit input-output ports. In input mode, pull-up resistor input, pull-down resistor input, or high-impedance input is selectable for each bit. In output mode, P-channel open drain output, N-channel open drain output, CMOS output, or high-impedance output is selectable for each bit. P9.0 to P9.3 and PA.0 to PA.3 are applied to the ML63189B only.

Setting this pin to "H" level puts this device into a reset state. Then, setting this pin to "L" level starts executing an instruction from address 0000H. A pull-down resistor is internally connected to this pin. Test TST1 I TST2 I Input pins for testing. A pull-down resistor is internally connected to these pins. The user cannot use these pins. 63 64 89 90 88 89 90 91 84 85 86 87 81 82 76 79 80 ML63189B ML63187 75 76 77 78 71 72 73 74 63 64 58 61 62 — — — — — — |
