2.4.7.12

RSPI

Note 1. tPAcyc: PCLKA cycle

Note 2. When a letter “-A”, “-B”, etc. to indicate group membership is appended to the pin name, each pin is recommended to use in

combination with the pins in the same group. All RSPI AC timings are measured in combination with the pins in the same group.

Table 2.43

RSPI Timing

Conditions: VCC = AVCC0 = AVCC1 = VCC_USB = VBATT = 2.7 to 3.6 V, 2.7 V ≤ VREFH0 ≤ AVCC0,

VSS = AVSS0 = AVSS1 = VREFL0 = VSS_USB = 0 V,

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

Output load conditions: VOH = 0.5 × VCC, VOL = 0.5 × VCC, C = 30 pF,

High-drive output is selected by the drive capacity control register.
