RSPIA

Note 1. tPAcyc: PCLKA cycle

Table 2.38

RSPIA Timing

Conditions: VCC = 2.7 to 5.5 V, AVCC0 = AVCC1 = AVCC2 = 3.0 to 5.5 V,

VSS = AVSS0 = AVSS1 = AVSS2 = 0 V, Ta = Topr,

PCLKA = 8 to 120 MHz, PCLKB = 8 to 60 MHz,

Output load conditions: VOH = 0.5 × VCC, VOL = 0.5 × VCC, C = 15 pF,

High-drive output is selected by the driving ability control register.
