Table 2-2. Terminal Functions PIN SIGNAL NAME TYPE(1) PULL(2) GPIO(3) DESCRIPTION NO. External Memory Interface (EMIF) Address and Control EM_A[0] 91 O - N EM_A[1] 89 O - N EM_A[2] 88 O - N EM_A[3] 86 O - N EM_A[4] 84 O - N EM_A[5] 83 O - N EMIF Address Bus EM_A[6] 80 O - N EM_A[7] 79 O - N EM_A[8] 76 O - N EM_A[9] 75 O - N EM_A[10] 93 O - N EM_A[11] 74 O - N EM_BA[0] 96 O - N SDRAM Bank Address and Asynchronous Memory Low-Order Address EM_BA[1] 94 O - N EM_CS[0] 97 O - N SDRAM Chip Select EM_CS[2] 100 O - N Asynchronous Memory Chip Select EM_CAS 37 O - N SDRAM Column Address Strobe EM_RAS 98 O - N SDRAM Row Address Strobe EM_WE 38 O - N SDRAM Write Enable EM_CKE 71 O - N SDRAM Clock Enable EM_CLK 70 O - N SDRAM Clock EM_WE_DQM[0] 39 O - N Write Enable or Byte Enable for EM_D[7:0] EM_WE_DQM[1] 67 O - N Write Enable or Byte Enable for EM_D[15:8] EM_OE 104 O - N SDRAM Output Enable EM_RW 102 O - N Asynchronous Memory Read/not Write (1) TYPE column refers to pin direction in functional mode. If a pin has more than one function with different directions, the functions are separated with a slash (/). (2) PULL column: IPD = Internal Pulldown resistor IPU = Internal Pullup resistor (3) If the GPIO column is 'Y', then in GPIO mode, the pin is configurable as an IO unless otherwise marked.
