Can a teensy 4.1 have two SPI buses running simultaneously

[kg4rul]

In am trying to add several SPI devices to the TSW Teensy 4.1 Raduino Clone board. The display is hard-wired to the TFT display so the pins D11/D12/D13 are not readily accessible. If I can have a second SPI bus on the accessible D37/D38/D39 pins it greatly simplify things. Is this possible?

in the TT1060 datasheet
there is two separate SPI units called A and B
they can be mapped to different pins
(not sure if the pin mapping is available in the Arduino framework)

Those pins on their own won't be sufficient for SPI1.
The four SPI1 pins on the T4.1 are:
D0 CS1
D1 MISO1
D26 MOSI1
D27 SCK1
As shown here and on the card that came with your T4.1

+Correction: pins 38 (CS1) and 39 (MISO1) are alternates.
