8 / 117 page 8/117 ST7285C 33 PF0 I/O Port PF0 - Software selectable as triggered input, a push pull output, open drain output, or triggered in- terrupt input with pull up (Interrupt I2). 34 PF1 I/O Port PF1 - 35 PF2 I/O Port PF2 - 36 PF3 I/O Port PF3 - 37 PF4 I/O Port PF4 - Software selectable as a triggered input or as a push pull output. 38 PF5 I/O Port PF5 - 39 PF6 I/O Port PF6 - 40 PF7 I/O Port PF7 - 41 VSSP Ground for Output Buff- ers. - This pin is connected to pin 1. 42 VDDP Power Supply for Out- put Buffers - This pin is connected to pin 2. 43 AINT Reserved - Must be tied to 5V 44 ARS Reserved - Must be tied to 5V 45 PG0 I/O Port PG0 - Software selectable as triggered input or push pull output. 46 PG1 I/O Port PG1 - 47 PG2 I/O Port PG2 - 48 PG3 I/O Port PG3 - Software selectable as triggered input, a push pull output, open drain output, or triggered in- terrupt input with pull up (Interrupt I1). 49 PG4 I/O Port PG4 - Software selectable as triggered input or push pull output. Note that PH0, 1, 2 offer alternate function capabilities for test purposes. 50 PG5 I/O Port PG5 - 51 PG6 I/O Port PG6 - 52 PG7 I/O Port PG7 - 53 PH0/ RDSQUAL I/O Port PH0 RDS Quality signal 54 PH1/ RDSCLKOUT I/O Port PH1 RDS GBS Clock Out signal 55 PH2/ RDSDATA I/O Port PH2 RDS GBS Data signal 56 PH3 I/O Port PH3 - Software selectable as triggered input or high voltage (10V max) open drain output. 57 PH4 I/O Port PH4 - 58 PH5 I/O Port PH5 - 59 RDSCOMP RDS Comp Input signal Used to feed the Demodulator from an external filter when the internal filter is switched off. 60 RDSFIL RDS Filtered Output signal Used for Demodulator test purposes. 61 RDSREF RDS Input Reference 62 MPX RDS input signal 63 VDDA Analog Power Supply For RDS and ADC circuits 64 VSSA Analog Ground 65 PA0/AIN0 I/O Port PA0 Analog input to ADC Alternate function or I/O. The I/O configuration is software selectable as triggered input or push pull output. Note that when a pin is used as Analog input it must not be configured as an output to avoid conflicts with the analog volt- age to be measured. 66 PA1/AIN1 I/O Port PA1 67 PA2/AIN2 I/O Port PA2 68 PA3/AIN3 I/O Port PA3 69 PA4/AIN4 I/O Port PA4 70 PA5/AIN5 I/O Port PA5 71 PA6/AIN6 I/O Port PA6 72 PA7/AIN7 I/O Port PA7 Pin Pin Name(s) Basic Function Alternate Fun ction Remarks |
