11 / 48 page  Electrical Characteristics MCF51CN128 ColdFire Microcontroller Data Sheet, Rev. 4 Freescale Semiconductor 11 3 Electrical Characteristics 3.1 Introduction This section contains electrical and timing specifications for the MCF51CN128 series of microcontrollers available at the time of publication. 60 — — PTG7 KBI1P7 FB_D1 — — 61 49 37 VDD4 — — — — 62 50 38 VSS4 — — — — 63 51 39 PTD4/RGPIO4 — — EXTAL RGPIO_ENB selects between standard GPIO and RGPIO 64 52 40 PTD5/RGPIO5 — — XTAL 65 53 41 BKGD/MS PTD6/RGPIO6 — — This pin has an internal pullup. PTD6/RGPIO6 can only be programmed as an output.1 66 54 42 PTD7RGPIO7 — SPSCK2 ADP3 RGPIO_ENB selects between standard GPIO and RGPIO 67 55 43 PTE0 KBI2P0 MISO2 ADP2 — 68 56 44 PTE1 KBI2P1 MOSI2 ADP1 — 69 57 45 PTE2 KBI2P2 SS2 ADP0 — 70 58 46 PTE3 KBI2P3 — TPM1CH0 — 71 59 47 PTE4 KBI2P4 CLKOUT TPM1CH1 — 72 60 48 PTE5 KBI2P5 IRQ TPM1CH2 — 73 61 — PTE6 KBI2P6 FB_D0 TXD3 — 74 62 — PTE7 KBI2P7 FB_CS0 RXD3 — 75 63 — PTJ0 FB_ALE FB_CS1 —— 76 64 — PTJ1 — FB_A4/FB_AD4 — — 77 — — PTJ2 — FB_A3/FB_AD3 — — 78 — — PTJ3 — FB_A2/FB_AD2 — — 79 — — PTJ4 — FB_A1/FB_AD1 — — 80 — — PTJ5 — FB_A0/FB_AD0 — — 1 RGPIO_ENB selects between standard GPIO and RGPIO. When PTD6 is set as RGPIO output, and "1" is driven to PTD6 via RGPIO function, a read of register RGPIODATA6 always returns a "0" because V1 RGPIO design looks for IO enable when the return value of RGPIO function reads data. As PTD6 is set to RGPIO output only, it returns "0" always to RGPIODATA6, athough PTD6 pin is driven to high. Table 2.
