15.3 Timing Parameter Symbology

The timing parameter symbols have been created

using one of the following formats:

FIGURE 15-3: LOAD CONDITIONS

1. TppS2ppS

3. T

CC:ST (I

C specifications only)

2. TppS

4. Ts (I

C specifications only)

F Frequency T Time

Lowercase letters (pp) and their meanings:

cc CCP1 osc OSC1

ck CLKOUT rd RD

cs CS rw RD or WR

di SDI sc SCK

do SDO ss SS

dt Data in t0 T0CKI

io I/O port t1 T1CKI

mc MCLR

wr WR

Uppercase letters and their meanings:

FFall PPeriod

HHigh RRise

I Invalid (Hi-impedance) V Valid

L Low Z Hi-impedance

C only

AA output access High High

BUF Bus free Low Low

CC:ST (I

C specifications only)

HD Hold SU Setup

DAT DATA input hold STO STOP condition

STA START condition

VDD/2

Pin Pin

VSS

RL = 464Ω

CL = 50 pF for all pins except OSC2, but including PORTD and PORTE outputs as ports

15 pF for OSC2 output

Note: PORTD and PORTE are not implemented on the PIC16F73/76 devices.
