15.5 Timing Parameter Symbology and Load Conditions
The timing parameter symbols have been created with one of the following formats:
1. TppS2ppS
2. TppS
T
F Frequency
Lowercase letters (pp) and their meanings:
pp
2 to
ck CLKOUT
cy cycle time
drt device reset timer
io I/O port
Uppercase letters and their meanings:
S
F Fall
H High
I Invalid (Hi-impedance)
L Low
T Time
mc MCLR
osc oscillator
os OSC1
t0 T0CKI
wdt watchdog timer
P Period
R Rise
V Valid
Z Hi-impedance

Pin
CL
VSS
CL = 50 pF for all pins and OSC2 for RC modes
0 -15 pF for OSC2 in XT, HS or LP modes when
external clock is used to drive OSC1
