18.13.15 Security Peripheral Select x Registers
This register can only be written if the WPEN bit is cleared in the Write Protection Mode Register.
The actual number of peripherals implemented is device-specific; refer to the “Peripheral Identifiers” section for details.
Each MATRIX_SPSELR can configure the access security type for up to 32
peripherals:
- MATRIX_SPSELR1 configures the access security type for peripheral identifiers 0–31 (bits NSECP0–NSECP31).
- MATRIX_SPSELR2 configures the access security type for peripheral identifiers 32–63 (bits NSECP0–NSECP31).
- MATRIX_SPSELR3 configures the access security type for peripheral identifiers 64–95 (bits NSECP0–NSECP31).
Reset values are as follows:
- MATRIX_SPSELR1: 0x000D2504 for H32MX, 0xFFF2DAFB for H64MX
- MATRIX_SPSELR2: 0x011C0000 for H32MX, 0xFFE7FFFF for H64MX
- MATRIX_SPSELR3: 0xFFFFFFFA for H32MX, 0xFFFFFFE7 for H64MX

| Value | Description |
|---|---|
| 0 | The selected peripheral address space is configured as “Secured” access (value of ‘0’ has no effect if the peripheral security type is “Peripheral Always Non-secured”). |
| 1 | The selected peripheral address space is configured as “Non-secured” access (value of ‘1’ has no effect if the peripheral security type is “Peripheral Always Secured”). |
