DS90UB936-Q1: Forward channel setting

Part Number: DS90UB936-Q1


Hi TI team,

I would like to use the GPIO0,1, 2 of DS90UB935 as forward channel to transmit the I2S signals (BCLK, WS, SD).

For the remaining GPIO3, can it be set to back channel for ISP reset function ?

I was confused from the table 99 of DS90UB936 datasheet about the number of enabled forward channel GPIOs.

The register 0x59[1:0] just can be set to ONE, TWO and FOUR GPIOs. no THREE!

So for my application, do I need to set 0x59[1:0] to 11:Four GPIOs ? and remaining GPIO can it be set to back channel ?
